I like most things about it but did not hold up long.

The cool design and it being part of a big company like Corsair makes you think you’re getting something of value. But no the mouse has gotta be the worst thing to exist what kind of mouse just disconnects mid usage fully charged and can’t reconnect. If you’re looking for something to blame your losses on get this mouse because when it disconnects mid game and you got ogres yelling in your ear about you throwing just tell them oh I’m using a Corsair product and they’ll completely forgive you

great mouse. it replaced my wired version of the m65

Omg sooo cute luv it i like it a lot its sooo nice

At first I really liked this mouse. The different speed functions are great to use and be able to quickly select through. After several months of use the mouse no longer holds a charge and I have to leave it plugged in 24/7 to use like a wired mouse.

I bought this to replace my old wired Corsair M65...big mistake. Get the wired version, the tracking and consistency just isn't there. I swear my cursor snaps off of targets due to lag, it just feels off

Mouse fits in hand ok, but the button layout is just awful. I couldn’t adjust what everything does like you can with other gaming mice which means when trying to go forward/backwards on things you change sensitivity, another set of buttons changes profiles? for the sensitivity which is useless, but worst of all just moving around the mouse your finger hits the buttons to change sensitivity which makes it unusable to me.

The M65 RGB Ultra Wireless mouse is hands down the most comfortable mouse I’ve ever used. I couldn’t be more pleased with a gaming mouse than I am with the M65. The mouse has so many features that make it stand out as one of my all-time favorites. Starting with the design of the mouse, it has a great shape that fits perfectly in my hand. All the buttons are in reach without having to move my hand up or down to push them. The soft rubber-like feal gives the mouse a nice grip and prevents it from slipping. The left and right clicks have a mechanical click to them, not only does it feel great, but it also has a distinct sound. The wheel has a nice thick rubber lining and give slight feedback when scrolling. One of my favorite features is the sniper/options button right below the back and forward buttons. This adds a whole new level of gameplay when playing FPS. The bottom of the mouse is equipped with 3 tunable weights, which you can manually adjust for your own perfect comfort level. And speaking of adjusting, the mouse has 5 different levels of DPI that can be adjusted to give you faster or slower control. Not to mention, the M65 has a built in six-axis gyroscope that enables tilt controls. The M65 can be connected 3 different ways your computer, first is the wired connection via the included USB-C cable. Second, via the USB dongle that offers slipstream wireless for hyper-fast inputs, and lastly you can connect it via Bluetooth for everyday normal use. When setting up the mouse you can personalize many features on the mouse through the iCue software. For example, you can customize the buttons, set custom lighting schemes, update the firmware, and even calibrate the tilt functions of the mouse. Overall, I couldn’t be more impressed with the M65 Wireless mouse. The design is extremely comfortable, and the soft rubbery feel makes it easy to grip and control. The ability to connect it through Bluetooth is a very welcomed add-on. The tunable weights, give the mouse great precision control and the six-axis gyro is an awesome feature for motion gestures. This mouse is a must have for not only gamers, but everyday users as well.

Eh nothing incredibly special but a nice wireless mouse.

Pro: -Great solid construction -Weight tunable -Bluetooth and wireless -Tilt gestures Con: -Shorter grip -Clicks are a bit soft This mouse is well built and has a good heavy heft to it, even without the added weights. The aluminum build feels solid and doesn’t have any creaking or hollowness to it at all. I prefer heavier mice for most of the games and even work, so I really liked how this mouse feels. However, for my palm grip, it’s too short to grip on comfortably. The mouse is about an inch shorter than my other gaming mice. I have slender hands and even so, most of my palm is not touching the mouse and it’s slowly shifting further back. I see this being more suited for a claw grip. The clicks are responsive, but also feels lighter and softer. The sniper button could maybe be a bit further back, but these are nitpicks. It has tilt gestures that you can assign actions to which can be useful, but I didn’t use them. The battery life seems good. I used it for a while and never had to charge it. The slipstream receiver can link other slipstream devices together but the range is short and needs direct line of sight. I have my tower right next to my monitor and plugging it in the back would cause dropouts. The mouse can either be used with the receiver or bluetooth with a flick of the switch. The iCue software lets you do surface calibration, tilt gestures, and of course the RGB. I’ve used iCue for a long time and I don’t have any negatives to say about it. The UI can be better, but overall it works fine. I’m somewhat ambivalent about this mouse. I like the build and the heavier weight, but the shorter design is clearly made for a claw grip. While a palm grip can still use it, it wasn’t that comfortable for me. It’s still a good mouse if it fits your grip.

worked great for the first couple months, then the right click stopped working. contacted corsair twice, with no response. jumped through all their loops for resetting, reinstalling software etc. still doesnt work. definitely not worth 130 for a few months of use.

This Corsair mouse is an excellent gaming mouse that's awesome for FPS games and everyday use. Battery life is decent, it's very responsive and has an excellent overall feel that doesn't fatigue your hand. The optical switches and the quick strike buttons do seem more responsive than my older mouse that has normal mechanical buttons. I would describe it is more precise in terms of when you click the lag time is minimal. You'd definitely benefit from a mouse like this if you have a high refresh rate monitor and play FPS games where milliseconds do count. Like other Corsair products, iCue gives you full control over the available key assignment settings, profiles, RGB colors and more. This mouse has the ability to connect via the slipstream USB dongle and Bluetooth. This mouse does have weights so it does feel heavier but that's one of the reasons to consider this one for FPS games, where precision movement is required and this mouse definitely has the right feel for my preferences in CS:GO. This is a solid mouse overall with the feel and the optical switches making it worthy of considering for an upgrade, especially if you play FPS games. I'd absolutely recommend this mouse!

Good mouse and I love the colors on the mouse. Great Christmas Gift!

bought this mouse, and it worked well for a month and it suddenly won't register when I'm moving it. So I returned it and got a new one with the warranty. And again worked well for 2 months and had the same problem.+

Setup: Pretty simple. Was able to insert weights for a heavier feel or remove them if I wanted a lighter mouse. Installed software via web search. Configuration was a little complicated. I did not find it very user friendly. Use: I thought the mouse had good feedback and the shape was comfortable in my hand. In use gaming it felt responsive and the special "fire" button was very responsive. I just felt that there was a click when pressing the different buttons that became annoying. After some use that did not go away. Overall it is just ok. I would recommend if you are sticking with the Corsair brand or like the adjustability of the weights. Cons: I did not like the loud button press sounds and the software was complicated to setup the additional buttons so I did not make use of them. After use there was visible oily residue on the mouse that made it look dirty. Would have wished for a different material to hide that.

Recieved item in good package. The only problen the usb pord does not function. I can not charge it or connect it to icue. Lol its worthless junk.

The Corsair M65 is the best mouse I have ever used. I don't think such a thing as the "perfect" mouse exists, but this is close. Ergonomics are a personal thing particularly with gaming mice. But the M65 falls into my hand like it was meant to be there. Very comfortable and the buttons are placed perfectly. I also love the adjustable weights for fine turning the "feel" to your liking. Also, the battery life has been awesome so far. Using the iCue software is a must. It allows for a lot of customization. RGB lighting on a mouse isn't really a big deal to me. But you can really customize the lighting a lot. Also (and more importantly) is the ability to fine tune the DPI. Using the M65 for everyday computing works great as well. I've been using it for both gaming & general use and have had no issues in use or comfort. But realistically, general web browsing isn't something you would really buy this for. All in all, I couldn't be happier and I can highly recommend it.

would not connect via blutooth or wifi. would only connect when plugged directly in. kind of defetes the purpose of spending extra money for wireless

The mouse would be good if Icue wasn't horrible. It never works. Every time the mouse goes to sleep it resets the DPI settings. I've been having this problem for years and Corsair can't seem to fix it. Honestly, i'm done with Corsair. They can't fix a problem no other software seems to have. Dont waste your money.
