Customer Ratings & Reviews

The mouse is small for my hands (XL hands) but it's perfect for finger tip grip. It's a bit narrow so my hand does cramp a little bit but the lightweight of the mouse eases a lot of those issues at least. Clicks are actually quiet and crisp. Body and shell is sturdy and strong with no creaking. Clicks and movement feel instantaneous and it's all configured in their web app like the Vanguard Pro 96, which means you don't need to run icue in the background or use icue to configure it to memory. Don't mind the mouse feet photos: i messed up when i was removing the original ones and replacing them with the in package skates.

Lightest mouse i have ever owned. Very quick and responsive. I would definitely use the provided grips. The bad thing about this mouse is the batter life. I only get about 2 days of use before i have to plug in. No warning that the battery is low. It just stops working.

Excellent mouse—quick, lightweight, and offers exceptional grip and control.

While it’s not perfect in some areas I do think Corsair finally knocked it out of the park with the Sabre V2 Pro. Let’s get into it - What will shock you the most when you first pick up this mouse is just how light it is. It certainly is the lightest mouse you can buy at Best Buy (at the moment of review) but what I want to focus more on is how Corsair finally made a proper eSports focused mouse aimed at purely performance. There were some attempts in the past with the M75 Wireless/Air but it just launched at a high price and I felt like it wasn’t totally finished. You could also say the same for the previous Sabre which had a different shape. For the retail price this thing checks a lot of boxes! - Insanely lightweight (34.94g on my scale) with NO HOLES - Very good small-medium shape aimed at claw grip - Decent but not amazing buttons - High-end sensor Corsair Marksman S sensor (up to 33k DPI) - Up to 8K polling rate with the dongle included! - Solid mouse skates (with an extra set in the box) - Solid battery life even on 2K polling rate - Web app that’s very easy and convenient to use Design: The design of this mouse feels like magic. It takes lightweight to a new level you didn’t think was possible. There are no holes and the coating is just textured plastic. On my unit it doesn’t even rattle though some creaking/easy bending of the plastic is possible especially by the top where your palm rests. Long term durability could certainly be a question mark. The shape of the mouse most reminds me of a slightly modified Razer Cobra but with more flair towards the back making it generally more suited for claw-grip. It’s a very agile aiming experience using this mouse in FPS games (I use a low sensitivity, but I was able to move a lot faster with this mouse while maintaining control. Buttons: For the buttons this mouse uses Corsairs brand new mechanical switches. While I wished they were optical for better durability these still sound and feel decent. Should definitely get the job done. For FPS gamers it’s probably going to matter more how light the clicks are anyways and these are just that which is good. Performance: The mouse tracked and worked flawlessly. I tested it at max of 2K polling rate and never found any hiccups or stutters. The only thing I find strange is that you’re not able to adjust your Lift-off-distance so I guess Corsair wanted to go for a more simplistic approach. Mouse skates: I found the glide to me nice and smooth on most pads though I recommend these work best with any control pads. I also like how there is a extra set of pair in the box in case the original get worn down. Software: Well uhhh it sort of doesn’t need one! I just used the CORSAIR WEB HUB which you can use on a browser. I was able to adjust all my settings very quickly and everything was saved onto the mouse. This is the way to go! Battery life: 70 Hours. The lower the polling rate the more time you will get out of it. Closing thoughts: I test a lot of gaming mice and this mouse stood out which is saying a lot if you know me. I’m happy that Corsair finally has a mouse like this so it’s a solid recommendation if you’re looking for a superlight weight mouse. This particular mouse doesn’t really tie you up into any kind of ecosystem but if you already have a lot of Corsair stuff this would be the natural choice. Pros: * Design * Weight * Performance * Battery life * Value Cons: * Potential long term durability * Just average buttons

Wow, is there something lighter than Ultralight? Maybe Uberlight? I can't even tell you how light this mouse felt other than the initial unboxing experience, where I felt some heft to the paper frame as I pulled it out of the box, then as I pulled the mouse out, I could've swore it was just a shell or swappable casing for the actual mouse. It was that light. Where was the weight coming from? The actual braided cable and RF dongle. Crazy. The mouse really feels like a plastic shell rather than a mouse, it is THAT LIGHT. I still can't believe how light this mouse feels in use, you're going to have to calm your movements because any extra twitch, cough, sneeze or movement is going to register. Normally I use a heavy mouse, G502 X Plus which is probably 3-4x heavier and while I know its not the best mouse for accuracy, competitive gaming and long-term fatigue and performance, I've just become used to it. However, I am definitely excited to give this Sabre v2 Pro a spin once BattleField 6 launches in a few weeks. A few things to note: *I don't really like the fact the dongle needs a usb-c cable to connect it to your PC instead of just having a usb-c male connector that can then plug into a usb-c female to usb-a male. You basically need a cable just to plug in the RF adapter and the included cable is huge and heavy, or you have to provide your own shorter USB-C male to male cable (A or C). *There is no BT connectivity option like most Corsair mice, which is fine since this is really a mouse meant for gaming and is focused on that function. Adding more electronics means heavier mouse. *The mouse kit comes with larger teflon mouse feet that are larger than the default "U" shapes. This will give more glide and surface at the expense of heavier weight. It also comes with some rubber decals for the sides and LMB and RMB buttons which again gives some comfort in exchange for additional weight. *The mouse feels good overall, buttons are clicky, scroll wheel feels good but they are not going to feel as premium as your larger bulky mice. No RGB either, you get a little green LED that tells you the mouse is on, then it turns off to save battery life which Corsair says is 70 hours. *I use Corsair iCue software for all my Corsair gear, iCue Link etc. and the mouse was not detected. You have to use Corsair Web Hub which is a first for me to make advanced adjustments to the mouse. To make quick DPI adjustments, you have to long-press back button + RMB and you'll get 3 flashes that show dpi adjustment mode. Not great especially for on-the-fly changes but this is due to the limited bells and whistles on the mouse. *Charging requires using the same big dongle to charge it. I would not recommend trying to use this connected to a this massive braided cable, you will definitely feel the drag of the cable over the weight of the mouse and feel like you are fighting a dog on a leash the whole time. I'm excited to try out the Sabre v2 Pro to see if the trade-offs are worth it or not, but overall I'm starting to get used to the lightness already. Let's see if it ups my K:D ratio!!!

The Corsair Sabre V2 Pro Ultralight is built for speed, responsiveness, and minimalism, and it nails all three. The first thing you notice is how absurdly light it is. At 36 grams (~0.08 lbs), it feels almost weightless in your hand, making flick shots effortless and long sessions less fatiguing. The default mouse skates are small and function well, and Corsair includes a second set of larger ones, which give better glide (at the cost of maybe a fraction of a gram). The shape is symmetrical (except with side buttons only on the left), the matte finish resists slipping, and overall it feels great in the hand. Under the hood is Corsair’s Marksman S optical sensor that boasts up to 33,000 DPI, with support for 8,000 Hz polling (0.125 ms latency). In practice, that means even the tiniest movements register instantly, giving you smooth aim and snappy clicks. Battery life is solid at a claimed 70 hours on the default 1,000 Hz polling. Push it to 8,000 Hz, and you trade some battery life for maximum responsiveness. Connectivity is via a 2.4 GHz dongle (no Bluetooth). The dongle design is clever: it can clip to your mousepad via a short USB-A to USB-C cable to reduce interference. I had mine connected to the back of my gaming tower under my desk and still had no issues with interference or latency. Overall, it may not have Bluetooth or flashy RGB, but the Sabre V2 Pro Ultralight is a no-frills, high-performance mouse that balances simplicity with excellent performance and feels great whether you are gaming or just working at your desk.

I don’t think I have ever felt a mouse so light. If you use this in wired mode, the wire on the desk feels heavier than the mouse. Good thing it only needs that for charging. Also it is a nice thing that it comes with grip tape, as it almost feels like I’m not holding it with it being so light. But, this included grip tape, that you can apply yourself on the sides and/or buttons, makes it feel much better in my hand. You can also choose to change out the default skate pads on the bottom of the mouse for ones that have more surface area. Personally, I feel the default ones were just fine and due to the way they are applied, it’s not like you can just swap back and forth. Corsair has introduced a way to modify your devices on the web now, with CORSAIR Web Hub. It is strange to me for a website to be able to modify hardware, but it provides all the settings you are used to without having to have some other app running in the background, like iCue. I wish this mouse had a separate button for DPI cycle though, as you have to use one of the two side buttons or the mouse wheel click as a custom setting if you want to cycle through them. You can have up to 5 dpi steps, from 100 up to 33,000 which to me feels insanely fast. With the Web Hub you can also customize macros to assign to the buttons and set them to specific profiles. Through the settings you can change the polling rate as well and how fast it can go to sleep, which can impact battery life. But, at default you are looking at days worth of continuous use. Overall, this thing is insanely light and fast. I feel it could be even more ideal if it has 1 or 2 more buttons to change DPI and/or profiles, but you can change all that through a web browser now.

The Corsair Sabre V2 Pro mouse isn't anything special. It's a functional, comfortable gaming mouse and lightweight at 36g, but otherwise for the price its features aren't that notable. My current mouse, Razer Viper Ultimate, from 2021 is still a better mouse. Moreover, the Dareu A950 Wing is practically the exact same mouse as the Corsair Sabre V2 Pro, and you can buy it for a much cheaper price. Starting with the pros, the Corsair Sabre V2 Pro is a comfortable mouse as a palm grip user. It feels smooth to maneuver around, and you can adjust how it feels with the inserts provided. You can use the mouse wired or wireless and even when wired it's in 8k polling mode. Whether or not you can feel the difference between 8k and 1k polling mode is debatable though. Battery life is generous at 70 hours for 1k or 16 hours at 8k, but compared to other gaming mice in the price range it's nothing notable. One of the first cons I have with the mouse is that there is only a 8k wireless USB dongle included. It's bulky and not very portable despite how lightweight the mouse is. Some of the other Razer mice(within the price range of this Corsair mouse) offer both a portable 1k dongle and a 8k dongle. Worse is that the USB cable isn't braided so it lacks flexibility and wired mode isn't as comfortable to use. Moreover, there's no dedicated button to switch DPI modes on the fly - you have to hold down the right click button and press the back button. This can be awkward if you switch DPI ingame. Finally there's no dedicated downloadable software to make adjustments to the mouse. You have to use the Corsair Web Hub so if you're offline and need to change key assignments, macros, the polling rate - you're out of luck. If you find the mouse on sale, the Corsair Sabre V2 Pro isn't a bad choice. However for the MSRP price, there are much better gaming mice you can find from other companies.

The Corsair Sabre v2 Pro is a fantastic gaming mouse. It's extremely lightweight, weighing only 36 grams. These lightweight mice are the trend nowadays. The mouse I received was reporting to be only 34-35 grams on my scale. There is no lag to speak of. Whether you use it wired while charging, or wirelessly, there is no noticeable difference in performance. All the settings have to be done via a web browser. There is a drawback to this. If your internet is out, and you want to make changes, you will be unable to do so. But there is also an option to download the web page as an app, which I highly recommend. The Web browser page is very easy to navigate and gives you access to all the settings for the Sabre v2 Pro. You get access to different profiles, key assignments, dpi settings, and also a macro manager. I'll be honest, I was a bit disappointed that the normal iCUE software was not able to access this mouse, because all my other Corsair peripherals are easily accessible via that app. Now I have to go between two separate apps/web page. Like stated earlier, the mouse is very light, and it is very ergonomic, but for me, it is a bit on the small side. If you have large hands, this might not be for you. I have found this mouse to be my perfect travel mouse when I take my laptop with me. It's still very precise, no lag, and has excellent battery life. The sensor is capable of up to 33,000 DPI with 50 DPI steps. I have found my sweet spot to be 3550 DPI, which works for me in my tight desktop space. You can also adjust the polling rate. Your choices are 1000 Hz, 2000 Hz, 4000Hz, or 8000 Hz. When gaming, of course I set it to the highest, but sometimes I forget, and even the lowest setting of 1000 Hz works amazing for me when gaming. I usually keep it at 1000 Hz to prolong the battery life. I have no idea if this a big impact at all, but it just seem like the thing to do. Overall, this is a fantastic super lightweight mouse that has a lot to offer for any serious gamer.

I have been using the Corsair Sabre V2 Pro Ultralight wireless mouse for a little while now, and so far it has been a good experience. I have used lightweight mice in the past, but this takes the crown. My other lightweight mice are a Logitech G Pro Superlight X2 and a Razer Deathadder V3 Pro Lightweight. The G pro is 24g heavier and the Deathadder is 27g heavier than the Sabre. I was very surprised when I pulled it out of the box and held it in my hand. The mouse also Included with the mouse are a USB-A to USB-C charging cable, USB-C receiver, PTFE bottom replacement, and adhesive backed grippy pads. The mouse weighs in at a featherweight 36g, comes with Corsair’s Marksman S 33K sensor, 8K polling rate, and Logitech’s Lightspeed Hero2 sensor, a 2kHz polling rate, and a solid 70hr battery life. Pulling the mouse out of the box I got an immediate sense of how light it was. It felt like nothing was in my hand, and its hard to explain that to someone without showing them. I actually brought it into work where several coworkers are also PC gamers, and they had similar reactions. As far as the form factor and feel, it actually feels very close to my Logitech G Pro. It’s a little narrower on the palm and the mouse buttons slope down a little more sharply, but it feels really close. The mouse has 2 side buttons and a clickable mouse wheel. Other than that there is jus the power switch on the bottom. The plastic shell has a light texture to it, but doesn’t feel very grippy. However, the lightweight nature of the mouse means you don’t need much grip to move it around. However, the included grippy pads can rectify that right away if you need it. Configuring the mouse is done through the Corsair Web Hub, which loads in your browser. My regular browser is Firefox, but it requires Chrome, Edge, or Opera to run it. iCue support is coming in the future but its not currently there yet. The Web Hub lets you assign the functions of the mouse buttons, set the DPI stages, and create macros. You can cycle through the DPI stages by long pressing the RMB and holding the back side button for 3 seconds. The LED in the scroll wheel will change colors for a few seconds indicating the new level. The default is 5 DPI stages, but you can adjust that from 1-5 stages in the app. The macros you create can be assigned to the side buttons, scroll wheel button, or the RMB. The LED under the scroll wheel is only lit up when changing the DPI or if you have the mouse plugged in to charge. Other than that it will start breathing red when the battery gets low. Using the mouse has been a good experience. After a little bit of use the extreme lightness is no longer felt, unless I pick the mouse up. I assumed I would have a little trouble with overshooting my aim point, but I was able to get used to it quickly. The mouse buttons feel nice and clicky. Actuation force feels pretty good and its got a sharp click sound. The scroll wheel takes a firmer press to click, but still is easy enough. Rotating the wheel is has a nice, soft roll to it with plenty of steps The PTFE skates on the bottom slide around well on multiple surfaces – not just a mousepad. I haven’t had any issue with the sensor not picking up movement – even when used on my granite countertop. Ergonomically the mouse feels great in my hand. I have always stuck with my G Pro because I liked the feel, but the Sabre really does a good job of matching those good ergonomics. Playing games with Sabre has been a good experience so far. I haven’t noticed any phantom movements in games when the polling rate is set high – no shuddering or induced twitchiness. I game on a large ultrawide screen so traversing the area can lead to lots of pick ups unless I set the DPI higher. Some games I don’t like to do that, so having a lighter mouse means the pick ups are easier, and quicker. You really notice it with heavier mice, so having an ultralight mouse is a bonus in these games. I had a short transition period where I had to acclimate to the feel of the mouse, but after a short bit I was completely comfortable. So far I have played mainly FPS games, which I don’t tend to bind any macros for. However, I did bind a macro to the wheel in one game, and it worked pretty well. The accuracy of the Marksman S 33K sensor proved to be up the challenge. It had no issues keeping track of my movements regardless of how slight they were. The surface I used it on didn’t appear to affect its performance. 33K dpi with 8K polling on a wireless mouse is crazy high. Other mice I have used required them to be wired to achieve the higher polling rates. For my gaming sessions I can get by for a very long time before needing to charge. A 70hr battery life is enough to last me over a month before needing to charge it. If you ramp the polling rate up to 8k you will really cut down your run time, but it’s still enough to handle even the longest gaming sessions. Running out of battery mid-game really should never come up unless you perpetually forget to charge it. Overall this is a pretty good mouse. I have grown to like the lightness of it, which did take some time to adjust to. The mouse feels good ergonomically, and the buttons all have a nice actuation force and click registration. The only downside I see right now is I am not a huge fan of the browser based applet. I would rather have it pulled into iCue, which I already have running for other Corsair peripherals. For now though its not that big of a deal.

Review of Corsair Sabre V2 Ultralight Wireless Mouse At first, the v2 of Corsage Sabre stand out first as extremely light as holding on the hand, then how its buttons fits for each press. In the pack includes: 1. Mouse 2. Charging Cable USB-C - USB-A 3. Textile case 4. Warranty and Safety/Compliance Information 5. Alcohol Pad 6. Grip Tape 7. USB Wireless Receiver Setting up: 1. Connection can be done in two ways: 1.a. Connected via cable 1/b. Via Receiver to use as wireless. In this case the receiver is plugged in the same cable. 2. Setting DPI 2.1. Via combination of buttons of the mouse to change on the fly 2.2. Via Corsair Web Hub or iCUE software Mouse status and indicators consist for DPI and Battery. For DPI are built in and predefined in 5 states ranges from 400 to 2000, each states mapped to colors from RED, BLUE, GREEN, YELLOW, and PURPLE from low to high. In the similar mode, LED Colors of Battery has 4 levels, Battery Charging When Low, Battery Charging when Medium, Full, and Critical, Recharge Required. For each has mapped color of Breathing Red, Breathing Green, Solid Green, Breathing RED. Playing: It is very responsive and very sensitive as immediately sense movement on my wrist. As result playing game really can appreciate the quick changes or the response to the respective click. From playing game, it didn’t show effect of lag or dragging from one point to another. What I wish it were better: 1. Wireless Connectivity: It support 2.4GHz frequency, and for its best result, the design includes a Receiver. This is bit bigger than other brand that has based the connectivity as it includes a clip. With this would allow the gamer to place it most closely possibly to the mouse. However this is dependent on the the cable. Which makes the use case a bit redundant. For such case it is almost the same as plugging the mouse to the cable instead of using with the receiver. Secondly, the receiver is socket version for USB—C, needing separate adapter if want to plug directly to the pd, or using the included charging cable makes bit cumbersome around the PD adding one more entanglement between everything on the desk. 2. Changing DPI Stages on the fly: As changing it, its status change shows on the mouse light, During the game being focused on the screen, wish it is shown on the screen, or have haptic response. 3. Bluetooth Connectivity without Receiver. It doesn’t support direct connection via Bluetooth. Only via the receiver to use wireless mode. For final word, for the context of pro gamers, the mouse is remarkably light, It weight 36g, it feels as holding an empty shell of snail. In the same way instant response as click on each area of the screen.

Corsair are really stepping up their game lately. I have reviewed a few gaming mice now as a TIN member, and I've owned a Corsair M75 Air (their previous ultralight mouse) for a few years now. This Sabre V2 Pro is something special, though. #Unboxing and first impressions# The Sabre V2 Pro arrived in a pretty standard box. I was happy to see that Corsair continues their push to use as many recyclable materials in their packaging as possible. I was also pleasantly surprised to see that Corsair included grip tape/pads with the Sabre V2 Pro - this was a complaint I had with the M75 Air and I'm glad they've caught up to other manufacturers in this respect. The mouse includes a braided USB-A to USB-C cable and a uniquely designed wireless receiver. More on that in the next section. I remember the first 60g mouse I received (from another brand) several years ago and how it felt like it must have been a display shell that you'd see at a retail store, without all the innards. The Sabre V2 Pro takes that to a further extreme at only 36g. It's simply unbelievable that Corsair got this thing down to just 60% of the weight of what I considered insane just 3 years ago, and without resorting to extreme measures like putting air vents/holes in the shell itself. Despite being incredibly light, it does not feel flimsy at all. There are no creaks or hollow sounds like the M75 Air had. This is a clear improvement on every front from previous Corsair mice, and a significant step up from my previous go to ultralight wireless mouse from another brand. #Using the Sabre V2 Pro# First, the dongle: the Corsair Sabre V2 Pro comes with a unique dongle that has a USB-C female port and a clip to allow you to clip it to your mousepad or another cable on your desk. I've never seen this kind of clip on a dongle before and I think it is pretty clever. It's kind of predicated on your mousepad being large enough that clipping it to the edge won't interfere with mouse performance, but in my case that is true so it works perfectly as designed. Second, the software: There is none! I expected this to require an update for an iCue module but instead Corsair uses their new Web Hub solution for the Sabre V2 Pro. You just go to a Corsair website in a supported browser (Edge and Chrome are supported) and you can connect to the HID devices and configure all settings from there. It's not quite as full featured as dedicated software like iCUE (I wasn't able to configure separate vertical and horizontal DPI) but that was basically the only feature that was missing. One really cool aspect of this arrangement is that you can fully configure the mouse from a locked down PC (as long as corporate doesn't lock down browser connection to HID devices...). A minor quibble for me is the mouse came with 5 DPI levels that were all pretty low - the highest being 2000 DPI. I realize the trend is for people to use really low DPI despite mice coming with 30K+ sensors, but I would rather have the mouse have the DPI setting a little more spread out instead of all 5 presets being 2000 DPI or below. Regardless, this is kind of a moot point since you can easily control these settings even from a locked down computer where you can't install software. In terms of performance, the Sabre V2 Pro works well in every respect. I play a lot of Overwatch 2 and also some Borderlands 4 lately, and in either game the Sabre V2 Pro was a nearly direct swap in for my previously-preferred ultralight mouse other than the lack of V/H split in the DPI settings (which only affects my Pharah config). I didn't feel any pixel skipping, and the 36g weight of the Sabre is fantastic for control purposes. The 2 biggest downsides to the Sabre V2 Pro are the battery life at 8K polling (which is pretty common for all 8K mice) and the cable design which pretty much makes it impossible to use for charging and playing at the same time. Normally you'd expect to be able to unplug the dongle and just drag the cable over to the mouse and use it in wired mode easily. The USB-C end of the braided cable is just way too long and the cable itself is pretty thick and stiff for this to be practical. On a mouse that has around 15-20 hours battery life in 8K mode, this is a pretty big hindrance if you don't have a better cable laying around somewhere. In 1K polling mode, the battery life will presumably be close to their 70 hour advertised life so this is a bit less of a concern. Plus, most people probably are not using the mouse for 8 hours a day for work like me, and then turning around and gaming with the same mouse all in 8K mode. Given the pretty competitive price for the Sabre V2 Pro, if you do find yourself needing to buy a better "charge and play" cable it's easier to absorb that cost considering this mouse has a lower MSRP than many competitors. #Final thoughts# The best gaming mouse I've ever used.

The power of this mouse is almost unmatched, the pull rate is great the lightness and responsiveness is by far one of my favorite characteristics. The lightweight and small design nature is even better, it allows me to slide it away in a hurry before my wife comes into my office at 2 am and beats me relentlessly until i go to bed. Good battery

I have used lightweight mice before. I wasn’t expecting anything new, and upon unboxing the Sabre V2 Pro, I was pleasantly surprised. This is the lightest mouse I have used so far. The mouse felt like one of those hollow toys you get at the dollar store, although significantly better than dollar store quality. This is my review of the Corsair – Sabre V2 Pro Ultralight Gaming Mouse. *TLDR at the bottom ========== IN THE BOX/SET-UP: In the box, you get a braided USB-A to USB-C cable, a wireless receiver with a USB-C input, attachable grips, mouse skates, and some documentation. Setup is straightforward. The mouse had about a 50% charge outside the box. The mouse can be used both wired and wirelessly. I decided to first use the mouse wirelessly. I connected the wireless receiver with the included cable and just like that, the mouse was ready to use! The receiver is on the larger side, but this may be due to the design choice of storing some of the wireless components in the receiver to help keep the mouse lightweight, which is understandable. Corsair’s iCue software is not needed for this mouse. Instead, a web app that goes by Corsair Web Hub is used, which I will go into more detail about later. ========== DESIGN: In terms of design, the Sabre V2 Pro is simple. The mouse is all plastic to keep it lightweight. There are forward and back buttons on the left side, and there is a power button located at the bottom. It is minor, but there is also an LED light inside that is only visible when hard-wired. The LED is visible wirelessly only when cycling through the DPI stages. ========== CORSAIR WEB HUB: The Corsair Web Hub is optional, but I highly recommend using the web app to fine-tune the Saber V2 Pro to your liking. The Web App can easily be accessed by simply Googling Corsair Web Hub. I recommend installing the web app shortcut on your desktop for easier access. The web app can also be used offline, which is neat! The UI is straightforward, and for this mouse, there are 4 main menu options: Key Assignments, DPI settings, Macro Manager, and General Device Settings. Key Assignments lets you assign functions to buttons, DPI settings lets you customize the DPI stages (5 stages), and Macro Manager lets you create and set macros. The General device settings show the battery life, polling rate settings, and more. For you RGB lovers, sorry, this mouse does not have RGB. Overall, the Corsair Web Hub app is extremely lightweight and easy to use. I love the idea of not installing software and simply accessing the mouse’s settings through a web app. I wish more gaming peripheral companies would end up moving to this model! ========== COMFORT/USE/BATTERY LIFE: The Sabre V2 Pro has been comfortable during long gaming sessions. I don’t play a lot of FPS, but I did play some Destiny 2 for testing. The lightweight of the mouse, combined with a high DPI setting and polling rate, felt great. A simple flick would make me do a 180, which is amazing for games like these. I also played some action-adventure games like Rise of the Tomb Raider, and the mouse certainly helped during intense combat scenes. One downside I had was the cycling of the DPI stages. To cycle DPI stages outside the web app, one needs to hold the back and right mouse buttons for 3 seconds. The mouse’s internal LED will then light up informing you of the cycle. This is slightly cumbersome to perform while gaming, and it would’ve been nice if this were swapped with a button on the bottom. I was also able to use the mouse outside of gaming while working on some of my personal home lab projects. I didn’t find the mouse too comfortable while using it as an office mouse. The mouse felt too light. It could be that I haven’t gotten accustomed to the mouse. What helped was hardwiring the mouse, which adds some cable drag and makes this more usable as an office mouse. As for the battery life, it is excellent! I have yet to charge the mouse. But I did notice significant battery usage when switching the polling rate to 8000Hz, which, in theory, makes sense. ========== CONCLUSION/TLDR: Overall, the Sabre V2 Pro is an excellent ultralight gaming mouse. This is the lightest mouse I have ever used, and I am overall glad how it has performed so far. The mouse performs great in games ranging from action-adventure to FPS. Setting the mouse’s DPI and polling rate settings to a higher option does feel like you are getting an edge. On top of that, the battery life is amazing, but be aware that a higher polling rate will drain the battery significantly quicker. Some minor downsides I found are the cumbersome process of cycling through the DPI stages outside of Corsair’s Web Hub and the lack of comfort with office tasks. But if you are looking for a dedicated gaming mouse that is lightweight in both weight and software (Corsair Web Hub), has a long battery life, and is customizable, don’t hesitate to try this one out!

This is the lightest mouse I've ever used, and I love the shape and weight. Accuracy is good. The included grips are nice as well. If you're a claw or fingertip user, I think this would suit you well. Extra bonus plans for the fact that you can program it over a web interface, so you don't need to install any bloatware on your PC to set up the mouse to your liking. Kudos for that and I hope more companies go this direction. The plastic is thin. Like, very thin. Like the noise can flex by pressing on it. But I suppose that's to be expected in something this lightweight. The only cons are it gobbles battery. 1000hz is pretty good. 2000hz isy sweet spot. 8000hz and you won't get a day of battery life. This wouldn't be so bad if they had included a decent cable. For some reason it has an awful, thick cable included to charge the mouse. Regardless of those couple of flaws this is my new daily driver, and I would recommend it, especially at its price point, if someone's looking for a lightweight mouse. For comparison's sake, my most recent gaming mice over the past couple years have included the G205 (lithium AAA), Deathadder V3, G Pro X Superlight, and Orochi.

Mouse is very lightweight. Accurate. Comfortable to use. Included grips are a nice feature for a secure feel. Wireless is plug and play and works well. The wireless adapter requires a usb c cable which adds bulk and may not be the best option for portability which is ideal in a wireless mouse. This is the only drawback in its designed functionality.

Great mouse, I'm using it right now it really is rediculously light and just glides over things with ease. I used all the aftermarket stick on stuff that was included. Its 8k polling rate is fantastic, if you leave it in 1k depending on your use you may get weeks wirelessly with out a recharge. This honestly feels amazing in my hand and extremely comfortable.

So far, I really enjoy using the mouse. With the included grip tape, it feels nice to use and it's very light. Battery life is pretty decent as long as you are not running 8k polling rate all the time. I have 18x10cm hands and this mouse shape is almost perfect for me. The shell does flex on the top of the mouse if you press down hard enough, however, I don't think this is an issue as you need a significant amount of pressure to push it down, which isn't likely while gaming. I definitely don't regret my purchase, it's good to see from Corsair.

For the price of $100, this mouse is rather lacking for its price range. In particular, it is not as good as my old Razer Ultimate Viper from 2022, which I will be making a lot of comparisons to. Worse, you can find a similar mouse for cheaper, the DAREU A950 Wing. I'll start with the pros, the mouse is comfortable for me as someone who uses the palm grip. It's very lightweight at 36g so maneuvering it around feels good. You also have grips that you can use to customize how it feels. The 8k polling works(wired and wireless) as advertised so your movements are very responsive. Whether you can tell the difference between 8k and 1k is debatable(even among the more competitive gamers), but if you're just the average user you probably can't. Now the cons. Switching between the DPIs on this mouse is done by holding down the right click and pressing the back button. Every other gaming mouse I have used in the past included a dedicated DPI. 70 hours at 1k polling mode isn't that impressive (16 hours at 8k) considering that's how much my 2022 Razer Ultimate Viper can do (other gaming mouses can do more). There is only one wireless dongle to use and 8k wireless dongles are generally huge compared to 1k wireless dongles that can be plugged directly into a USB port. Given the lightweight, this would make for an excellent portable mouse if it also included a 1k USB dongle that can be stored in the mouse like the Razer Cobra Pro or Razer Viper Ultimate. Finally you have USB cable. Unlike some of the other USB gaming mouse cables, this one is not braided so it lacks the flexibility that makes maneuvering the mouse easier in wired mode. At the MSRP of $100, I cannot recommend this mouse. You can get a better gaming mouse for this price or find the exact same features on a cheaper mouse such as the DAREU A950 Wing.
