Super light, clicky button, 8khz polling. What else you want?

Awesome mouse a bit bulkier compared to the super light but still really light also don’t need to charge it that often

The Battery life is very good so far, 8+ hrs a day for a week and only at 73% battery! Size and build is nearly identical to v3 as well. There are many options to toggle through for DPI but realistically you would stick to one to maintain consistency in FPS games so personally I stick to using just one setting. Since this mouse just came out recently, the price is kind of on the high end for my taste so maybe wait for a sale if you can, but you can’t go wrong with this mouse if you’re looking for a comfortable smooth mouse for work or gaming!

One of the best mice I have ever used and definitely the best ergo. Has an optical scroll wheel that is superior than the competition.

This mouse is super lightweight and the battery is superb. I have had the mouse for about a month now and have only had to charge it once. The grip tape is a nice addition to the mouse. I would definitely buy again.

Amazingly lightweight! With Synapse installed you can fine tune; Dpi, polling, all the way to custom macros.

best gaming mouse in 2025-2026. this mouse is god tier. a little pricy but if it’s in your budget area you have to get it. No ifs ands or buts. YOU HAVE TO.

Very lightweight and responsive. I like the white color.

Excellent mouse. Very light weight. Not budget friendly ofc but worth it.

Amazing mouse by far the best I’ve ever had the pleasure of using for gaming & just everyday

Blazing fast, ultra-precise, and loaded with pro features for ultimate gameplay

This mouse has been great it’s light and smooth can’t really ask for more from it

Wonderful mouse, pretty smooth, good sensor for an excellent price

The Razer DeathAdder V4 Pro is billed by Razer as the “Fastest Gaming Mouse.” The mouse has high polling and low latency dongle, an excellent grip, is ultralight weight, and is infinitely customizable and tweaked thanks to Razer’s Synapse software. I am not entirely sure how well some of these claims will truly translate into winning the next gaming session, but it is an impressive mouse. Unboxing: Razer includes the USB-A to USB-C cable, the new spherical dongle, and the mouse. Users should know that Razer’s Synapse software will tell users that they need to download the latest firmware updates from Razer’s website. So, in addition to Razer’s Synapse, expect a firmware update out of the box. Experience: This is an ultra-light mouse with a great grip. It fits my hand very well. The scroll wheel is elevated and precise. The mouse clicks register well. Razer implies that this is the most advanced mouse, and it may very well be, but in terms of gaming performance, the war for performance supremacy is apparently won in inches rather than miles. The leaps may be big, but they never seemed that big to me during my gaming sessions. This mouse feels great, but the shape and weight are not a drastic departure from what has come before. I think the thing that caught my eye the most out of the box was the new spherical dongle that Razer includes. Gone are the days of a nano dongle that you can easily slide into a USB-A port on the side of your laptop gaming PC. This sticks out. The three light indicators are super helpful and are customizable. It is at its best connecting to a desktop on the floor. The weighted dongle has a decent grip on it and will stay well on the desk. It seems a lot of the boosts to the mouse’s performance come down to this new dongle. The dongle is what allows for lower latency and higher polling. Polling is how frequently the mouse updates its positions and reports clicks to the computer. Personally, I noticed improvements at 2,000hz over the 1,000hz default, but I could not say that I noticed any gains after that. In addition, the higher the polling rate, the quicker the mouse’s battery will drain. So, this was, in my experience, a mixed bag of features. I did notice gains, but I am not sure it was enough to call it a “must-have” feature. Rather, the feature that I liked the most was the dynamic sensitivity toggles. How a mouse's cursor movement speed changes based on how quickly you move the mouse is the sensitivity curve. There is a traditional linear acceleration curve, a natural curve, and a jump curve. Or you could create your own. The “Natural” curve worked well in RTS strategy games while the “Jump” curve worked great for FPS twitch fests like Doom: Eternal. The jump curve provides the right amount of instant acceleration yet proved more stable once I was fine tuning my aim. I loved this feature. Battery Life: Battery life has been good, but again your mileage will vary depending on polling rate and usage. Averaging my usage out over five hours, I lost about one percent of charge every hour of use. Now if I turn polling back down, the numbers could improve. Conclusion: I have had many gaming mice over the years, but I keep coming back to Razer’s mice in part because Razer’s software is familiar and effective. It is rare that I ever have a problem with Synapse conflicting with drivers or software from other hardware manufacturers. In the case of the DeathAdder V4 Pro, Razer’s Synapse offers a lot of customization options for the mouse. The options are easy to cycle, and everything works just as I would expect for a mouse of this quality. I am not sure that the DeathAdder V4 Pro is the leap in performance that Razer claims it to be. It is good. It is my favorite Razer mouse to date. It is the mouse that I will use on my gaming desktop going forward. But the polling speed increases felt like a double-edged sword without much benefit. The new spherical dongle looks cool but is less convenient than the prior nano receivers. This is a great mouse. It is the best gaming mouse I have ever used. I do not know if all its features are truly going to be of much benefit to me, but I would still recommend the mouse to gamers demanding the latest and greatest gaming mouse features. Recommended 4.5/5

As someone who is on computers daily for work and leisure, I use quite a few mice because I use various computers. I have heard a lot of good things about the Razer DeathAdder line and this newest addition lives up to the hype. It is incredibly ergonomic, ultra-light, and highly customizable. Along with the mouse, the package comes with a wireless dongle, a 6ft USB-A to USB-C cable, mouse grip tape, and a guidebook. The mouse is made of smooth plastic with a rubbery grip scrolling wheel. I am so glad Razer included grip tape because I feel like I need the tactile textured grip. They can be easily repositioned upon initial installation but stay firmly on afterwards. Additionally, they help me keep a stable grip plus they have a soft, appealing rubbery feel to them. I used four of the five grip tapes because I did not know where the last one was supposed to go and the mouse seems perfectly fine without it. The mouse includes the two main buttons, the scrolling wheel that can also pressed like a button, two left-side buttons, and a power button underneath that doubles as a DPI stage cycle button. The buttons are clicky with a quick response. The ergonomic design of this mouse is well thought out because when I look at the shape my hand makes while using a different almost-flat mouse, it is the exact same shape Razer designed for the DeathAdder V4 Pro, except it’s just floating in the air. Thus, when I use this mouse, it does not cause tension or agitate my carpal-tunnel prone wrist. This mouse can be used either wired or wireless with the HyperSpeed Gen-2 dongle. The dongle includes 3 LED indicator lights, which indicate connection status, battery level, and polling rate by changing in color. I like that Razer included this because I am able to easily note if the polling rate is in the wrong setting and go back and switch it before I’m already in a game, as well as knowing when to charge the mouse so it does not die midgame. The Razer Synapse 4 is a great software and allows for almost every function of the mouse to be customized. Some of the many things that can be customized are sensitivity, rotation, DPI, polling rate, LOD, and button mapping. I tend to use my mouse slightly rotated to the left, so having the ability to calibrate my pointer to that is life changing. I am so used to compensating for this for so long though, that I have yet to adjust to the calibration. The Razer Synapse has the option to automatically adjust polling rates based on game by using custom-made presets, plus it has the option to switch it up whenever the computer goes on full-screen game mode. I like this because my family uses this computer for non-game purposes as well and I do not need a 1000+ polling rate during such usage, but I forget to change it back more often than not. The DPI is true to number; I tested it thoroughly. I have toggled through it during gameplay as well. It is a bit tricky to switch it midgame because it’s at the bottom, but I still love that I can change it at all using the mouse because I did not have this option with my last gaming mouse. The sensor is fantastic, tracking exceptionally well with the mouse hovering above the surface. Personally, I prefer a low LOD but those who prefer it high should place this mouse on their consideration list. Overall, the DeathAdder V4 Pro is a great way to maximize a gaming setup. It is almost completely customizable, has astronomical polling rates, can be used wire or wireless, is perfect for easing hand fatigue during long hours of usage, and so much more. I am kind of frustrated with my other mice at this moment, this one has spoiled me and I’m not sure how to deal with it because I do not need a gaming mouse for my other computers.

The Razer DeathAdder V4 Pro Gaming Mouse is the ultimate wireless gaming mouse. You have so much control of nearly every aspect of the mouse's performance. The DeathAdder V4 is very light weight, weighing in a only 57 grams. It's also very ergonomic and all the buttons are in the perfect location for my big hand. The Razer Synapse V4 software unlocks tons of options for the DeathAdder V4, and is easy to navigate. You can also setup macros and settings for specific games. You can set individual polling rates for games, from 125 - 8000Hz. I have mine set normally to 1000Hz when doing normal everyday stuff, and it jumps to 8000Hz when getting into FPS games like Call of Duty or other games like that. Sensitivity Matcher allows you to mimic the sensitivity of a different mouse. Let's say your previous mouse was setup perfectly for sensitivity, and you want the DeathAdder V4 to match that performance, you can calibrate it through the Synapse V4 software to be identical. You can also customize the mouse lift off points and how it reacts with the Mouse Surface Calibration option for more precision. I played around with the setting a little bit, but found the default options work of great for me. You also get access to Dynamic Sensitivity, which to me is an enhanced version of Windows "Enhance Pointer Precision". You get three preset options and a custom option for you to fine tune your preference. I found it to be useful in the small area I have next to my keyboard. It allows me to make bigger moves in a smaller space, and still have precision when you need it most. The wireless dongle has a very unique feature. It has three LED lights that can be customized to give you at a glance access to your mouse settings and battery life. I really like this feature, because I don't have to guess what DPI setting, how much battery, or what polling rate I'm at while gaming. Battery life is phenomenal at 150 hours with the recent firmware update. The only thing that would make this mouse any better in my opinion would little bit of RGB.

I currently own quite a few wireless gaming mice and have been amazed with the improvements with regards to weight, skates, and mouse settings (sensitivity, DPI, polling rates, and lift-off/landing distance). I have been a fan of Razer’s DeathAdder line and wanted to give the DeathAdder V4 Pro a try. The DeathAdder V4 Pro is listed as weighing 56 grams and I couldn't image any additional benefit from it weighing less. The mouse is very comfortable in my medium sized hand, but may be too large for small hands. The best thing about this mouse is the software. Razer Synapse 4 allows programing each setting for every game. It is nice to be able to change the settings for sensitivity and polling rates and save them. I do not play a lot of games which require polling rates higher than 2K Hz, so I can't speak for the added benefit of 8K Hz. I believe the 8K polling rate will only be significant for pro-gamers where a split second matters for combat games. As expected, there are multiple settings for DPI which can be important depending on the monitor and mouse pad used. I have found the lift-off/landing distance settings helpful when I am gaming in my recliner and do not have much room to move the mouse without lifting it up. I like the update Razer had for the HyperSpeed Wireless device. The 3 programable lights provide helpful information such as connection strength, battery, and polling rates. Since many gaming laptops lack many USB-A ports, however minor, I was surprised to find an included USB-A to USB-C instead of a USB-C to USB-C cable. If you are looking for an edge to help win, this is a great mouse. The battery life and lightweight of this mouse will allow gaming for hours. The ability to customize the settings and save them for each game is amazing and this mouse will not disappoint.

Razer, the manufacturer of award-winning high-performance gaming hardware, was founded in 2005 & operates headquarters in Irvine, California & Singapore. You get a glimpse of the extreme popularity of Razer by over 200 million users of their many software suites! The latest offering from Razer is turning the industry on its ear! The DeathAdder V4 Pro is a revolutionary breakthrough, with every specification that defies the status quo! For starters, this mouse is ideal for big/long hands. The ultra-lightweight design tips the scale at only 56 grams, more than 10% lighter than their previous award-winning model. Not only does this feel great in my hand, motion is fast & smooth. It feels immediately comfortable because it retains the shape of my beloved DeathAdder V3 Pro. The dramatic performance boost is augmented by Razer Hyperspeed Wireless Generation 2. At 8000 Hz, average latency is a minuscule 0.291 ms! Compare this with the previous Generation 1, which featured an average latency of 0.461 ms. Competitors' average latency is 0.807 ms. Thanks to a 63% boost in efficiency, DeathAdder V4 Pro provides 150 hour battery life! The scroll wheel, switches & sensor are all optical, producing greater reliability than mechanical designs. The switches are rated at greater than 100 million clicks! Razer Synapse 4 software enhances this amazing mouse in so many ways. Here are just a few: Sensitivity Matcher, Dynamic Sensitivity, & Mouse Rotation. CONCLUSION: The DeathAdder V4 Pro is hands down the best gaming mouse I have ever experienced & earns my highest recommendation.

The Razer DeathAdder V4 Pro is an update to the super popular V3 Pro. I used the V3 ever since release so I’m quite familiar with the shape and its various pros and cons. The new V4 is mainly helping to address and fix those complaints all while packing even more powerful hardware! Here is everything that was updated in the V4 compared to the V3 - - 56g weight ( -7g) - Gen 4 optical switches - Optical scroll wheel encoder - Side buttons - Bigger skates - New sensor (45K DPI) - 8000Hz Polling rate as standard - More software features More details and specifics - Design and weight: This is an ergonomic right-hand only mouse coming in at a very lightweight 56g. The shape is identical to the V3 Pro, but obviously differs a lot if you’re coming from the V2 or any other older classic DeathAdder. I personally much prefer the newer shape as it's much better for claw-grip. The coating now has a smooth-touch all around and is generally much more pleasant to the touch compared to the old coating which was a bit chalky. Performance: A shining point for Razer gaming mice is the performance you get as they are pretty much the first in the game to feature new optical sensors. The V4 Pro is packing a 45K DPI sensor which has a max IPS of 900 and 85G of acceleration. Pair all that with an 8000Hz polling rate and you get the most responsive gaming mouse on the market. I personally only use 2K polling as it's good enough for me and also saves on battery life. Latency all around felt really on point even with multiple wireless devices around me. This is truly an e-Sports ready mouse that I have no doubt many pros will use. Buttons: Two very important upgrades over the V3 come with the addition of gen-4 optical main switches and even more importantly an optical scroll wheel encoder. For the main switches they now feel a lot more crispy with a lot less pre-travel and less overall sponginess on the rebound. In terms of sound they also have a different signature that almost sounds mechanical so overall I’m super happy with them. For the scroll wheel the huge upgrade is that it's now optical just like the main switches! That means you will no longer have to worry about its reliability and any dust causing false inputs. Lastly for the side buttons they are now more spaced out and are slightly smaller which means they are easier to differentiate if you use them a lot in-game. Skates: The skates are now much bigger and out the box have a much nicer glide that is no longer rough. I always had to swap out the stock feet on my V3 as on most mousepads the experience was not that good. The V4 skates are on point though and everything felt great! (tested on cloth pads) Battery life: This will depend on what polling rate you’re using but expect about ~120 hours in normal operation. It’s also very good for standby. Software: You will want to use the new Synapse 4 which is overall much better laid out and less buggy compared to the old 3. There’s also some cool new software features like dynamic sensitivity and sensor rotation. - Dynamic sensitivity: This basically mimics mouse acceleration but is much more customizable so you can set exactly when you want your sensitivity to speed up. Now I usually play FPS games and the popular sentiment is that mouse accel is a big “no”. I would still experiment with this feature and see if you like it. For me it makes clearing angles in games much easier and effortless while still maintaining control for those fine movements. - Sensor rotation: I personally didn’t find much use for this but it's handy if you ever found the combination of the mouse and your grip style to cause the cursor to not go as straight as you wanted, so this can basically correct that. Build quality/QC: My unit is built very well. No creaking or rattles. While it may not seem like a big upgrade at first glance I can highly recommend the Razer DeathAdder V4 Pro - it should be a great mouse for years to come! Pros: * Shape * Weight * Performance * All the buttons * Battery life * Build quality * Unique software features Cons: * None

Coming from someone who’s been playing Counter-Strike since around 2001, I’ve used everything from ball mice to the iconic (what some may call the “GOAT” of gaming mice) Microsoft Pro IntelliMouse. The shape of the DeathAdder V4 Pro (and previous predecessors from the DeathAdder line up) really reminds me of the Microsoft Pro IntelliMouse. The Razer DeathAdder V4 Pro feels like a modern-evolved yet classic beauty that has met the demands of the current FPS scene. The Deathadder V4 Pro nails that slightly elongated, right-handed ergonomic design. If you grew up on the IntelliMouse like I did, this shape may make you feel right at home except with all the tech worthy upgrades under the hood. It’s more lightweight than its predecessor weighing in at just 56g. But don’t let the lightweight fool you. The Deathadder V4 Pro is sturdy and glides smoothly even under high-stakes flicks and micro-adjustments in CS2. Right out of the box the DeathAdder V4 Pro feels, looks, and performs beautifully. With the new HyperSpeed Wireless Gen-2 technology, you’re looking at more power efficiency and lower latency than its predecessor. With true 8000hz wired and wireless polling, you’re looking at faster and more accurate inputs. The DeathAdder V4 Pro also comes equipped with a 45k optical sensor as well. I am going to also highlight some of the stellar upgrades Razer has done under the hood. Razer has made some amazing upgrades to the switches and scroll wheel. The DeathAdder V4 Pro has Gen-4 optical mouse switches which means they have a 100 million click lifecycle (lets not forget to highlight the amazing tactile feedback on those clicks!). The DeathAdder V4 Pro also has Razer Optical Scroll Wheel which correlates to better accuracy, durability, and consistency in every scroll. Lets also mention the redesign of the dongle which now boasts better performance and includes three lights to show connectivity status, battery life and polling rate. Last but not least, the battery life on the DeathAdder V4 Pro is INSANE! I obviously don’t have some sort of timer set to where I am calculating this but just general usage (which includes work and gaming - “a lot”); I have been using this mouse nonstop for over a week and never once had to worry about charging it and this thing is still has more than 50% juice! One of the standout features is how customizable the DPI stages are. When using Razer Synapse to set up your DPI stages, you are able to fine-tune your sensitivity down to a 1-DPI increment. So what does this mean? Being able to perfectly dial in just the right feel to how you want your movements to move. Even mouse rotation adjustment is included. Why is this important? For those where minor details including wrist angle and desk posture can affect aim; this feature makes a measurable difference. Razer provides you with a tool (within Synapse) that can test how much rotation you are adding and by running this test and setting the difference in mouse rotation; you can now confidently draw that straight line in paint (mine was -2 degrees - who woulda knew?!?!). Another big win: I can set different polling rates for different games and with Razer Synapse, it auto switches between them depending on the title I am running. So for example while I am playing CS2; I set my Polling rate to 4000 Hz for raw response and input clarity, but generally like to bring down the Polling rate for more casual games where battery life matters more (higher polling rate means more battery consumption). When it comes to features and playing a game like CS2, sensor calibration is a game changer. I am a low sensitivity player that does relatively large swipes. The ability to calibrate both lift-off and landing distance separately with up to 26 levels is a huge win. I like being able to fine-tune mine to stop tracking the movement as soon as I lift which reduces unwanted cursor drift when repositioning the mouse. It’s essentially small tweaks that lead to huge consistency gains for me. Lastly on features, I’d like to touch on Dynamic Sensitivity. With this feature turned on, it automatically adjusts mouse sensitivity based on movement speed. What this means is it could offer higher DPI for quick flicks and lower DPI for when I need my aim to be as precise as possible. With the -2 degrees set for mouse rotation and Dynamic Sensitivity preset of “JUMP”, it allows both fast turns and accurate micro-adjustments all at the same time (180 - HEADSHOT!). Razer didn’t just throw tech specs at this mouse, they built a tool that adapts to the way YOU play. The DeathAdder V4 Pro hits that sweet spot between nostalgia and cutting-edge performance. Whether you are a palm or claw grip player, the DeathAdder V4 Pro will feel immaculate in your hand. Will you become a professional esports player by purchasing the DeathAdder V4 Pro? Maybe. But one thing is for certain. The DeathAdder V4 Pro is definitely something I would recommend if you are looking to truly customize your gaming mouse to fit all your wants and needs (and heck, possibly even your deepest desires).
