It’s an excellent mouse — very accurate, with tons of customization options.

It’s an excellent mouse — very accurate, with tons of customization options

If you got big hand, good mouse, fit palm real good.

Super smooth transitions while gaming. An essential to my experience.

Overall build of the mouse is great but having disconnect issues with the mouse as well as software not working or savinf settings.

I don’t like how clicky the mouse is. It’s very loud clicky noises. Other than that, everything else is amazing

It's crazy how many features a mouse can have but it's a lot. The cost is insane.

If you want something that is very light, go for it. It feels very cheap.

Very responsive buttons. all optical and ergonomic.

Great mouse, incredible quality. Two major flaws for me: no bluetooth and clicks are annoingly loud.

Super fast mouse! I love the grips that come with it also

Razer is one of the leading makers of gaming hardware, and they have built a new version of their eSports Pro gaming mouse, the DeathAdder. What features does it have, and what makes it worth the rather high price? Let’s send it through its paces and see if this is a tool for the competitive gamer’s arsenal. The box contents are straightforward, with the mouse, receiver, and a decently long braided USB-A to C cable, custom cut grip tape, Razer stickers, and some documentation. Setup is as simple as you’d expect – download the latest version of Razer Synapse, plug it in, and go! The mouse itself is incredibly light. A just 56g, it weighs less than most of the “skeleton” style mice and doesn’t collect things inside of it that you can’t clean out. Stripped down to save weight, it does not have a side-to-side scroll wheel or many extra buttons, just two thumb buttons, the right and left click, and the scroll wheel. The scroll wheel also has no “free spin” mode, but gains an optical sensor. The power button serves as double duty to cycle through the programmed DPI settings that you have set in the Synapse software, and there is no multi device connectivity with Bluetooth. This mouse is about one thing, and that is performance at minimal weight. While the mouse may be stripped to the essentials for hardware, the sensors and software allow for a ton of customization and performance. The mouse is capable of a blistering 8000hz polling rate with a 45k sensor, even while wireless. Usually, higher polling rates are reserved for wired connections, but the wireless technology here allows for an astonishing polling rate. This mode will drain the battery more quickly, but fortunately Razer thought of that – you can set different polling rates for full screen games vs standard desktop use. One of the coolest features I’ve found is the dynamic sensitivity mode “jump”, which allows for a lower sensitivity when the mouse is moving more slowly, which is great for aiming, but then jumps to a higher sensitivity when the mouse is moved rapidly, allowing for rapid 360 spins in a shooter when you need to react quickly. It’s a really cool feature that prevents having to bind a button to a “DPI Shift”. One thing I really like is, oddly, the receiver. Most of the time, the receiver is a little dongle or a box that doesn’t add much other than taking up a port or sitting on a desk. This one has status indicator LEDs that show connection health, current battery level, and the polling rate (these can be customized to show things like current DPI using Synapse). It also has some weight so it stays put. The only improvement would be if it had a second USB-C port to plug the mouse into directly to charge or switch to wired, since this dongle is designed to be on your desk. The surface of the mouse is pretty smooth – I’m used to mice with grips or texture of some kind, but again those can add weight. It’s still fairly easy to grip, but if you are super sweaty it could get slippery. Fortunately, Razer thought of that too, and there is pre-cut grip tape in the box to add some grip (with just a touch of additional weight) to key parts of the mouse. The optical buttons feel great, with a super snappy response. The mouse also has an optical scroll wheel that should mitigate one of the most common points of failure in gaming mice. The mouse will store the last binding configuration programmed in Synapse into it, although some key binds or macros aren’t available unless you have the software running. I typically use a gaming mouse for work where I can’t run any software, and this mouse probably would not be the best fit for that kind of multi-device or multi-purpose use as it really needs Synapse running and doesn’t have some of the extra buttons that are frequently used for productivity. For gaming though, this mouse excels. It moves so freely without feeling like it’s skating that you forget it’s there and just focus on the game. It so responsive and accurate that you know the limiting factor in your game is your skill, not the equipment. With that it mind, the mouse can justify the steep price tag while not having a lot of frills and extra features. It’s about one thing, and that is delivering a tool designed for fast paced competitive gaming, and if that is what you need this is the mouse for you.

I bought this for my son & he love it, I also love that brand

Everything was as advertised but the minimal improvements over the Deathadder V3 Pro, does not justify the $70 price increase. Great mouse if you're willing to dish out the money just to have the best of the best.

It's the same as the DeathAdder V3 Pro, but more expensive.

it performed and worked but i was not a fan. the mouse felt almost to light and very poor materials were used to make it. i did not enjoy the short time i had it and wouldn't buy another.

The build quality is a major upgrade going from the V3 to the V4 version. The coating the one of the best I’ve felt on a mouse. I wound up returning mine due to it developing creaking beneath the side buttons. I would wait until later batches to consider purchasing this mouse.

The Razer DeathAdder V4 Pro is a premium lightweight gaming mouse with a few nice improvements over previous generations. I have used several razer mice including a couple versions of the deathadder over the years and they have been consistently good products. Razer seems to take an approach with mice that when they have something to offer, something to change to keep up with the trends in gaming, they’ll release the new version. The Deathadder v4 exemplifies this concept while sticking to a familiar mouse shape many people love. The v4 is extremely light weight, extremely well built, and includes a 8000hz polling receiver in the box and adds an optical scroll wheel and a few software tweaks. The light weight of the Deathadder v4 is nice for competitive games where quick, snappy reaction matters like counter strike or call of duty. With recent monitors having high refresh rates and lower input lag, a mouse that is lightweight and snappy helps keep up with the responsiveness of the monitor. The build quality is great - no creaks or uneven clicks or other QC issues. The coating of the mouse is nice - it does not feel too slippery but also doesn’t have an overly rough texture. If desired there is some stick on rubber grip tape in the box. The mouse comes with a new 8000hz polling rate receiver with status lights on it. It’s a nice touch and the receiver is weighted to help it sit on the desk. When it comes to 8000hz polling rate, the best illustration of what polling rate is, is to go in razer synapse and set it to only 125hz. Move the mouse around and the movement doesn’t have the same precision as before. Typically gaming mice are set around 1000 which is fine for most scenarios, but on a high refresh rate monitor like the current 240, 360, 480hz monitors, its nice to have a mouse that keeps up with high frame rates and refresh rates in games like counter strike or call of duty. Another nice improvement is the optical scroll wheel. Scroll wheels often seem like an easily worn out part of a gaming mouse which can be annoying to have a perfectly good mouse start scrolling poorly. I highly suspect the optical technology here will be a huge long term reliability improvement and it’s a welcome thing to see. Razer updated the synapse software to version 4 a few months ago. Synapse 3 sometimes felt like it was a bit of a system hog but version 4 doesn’t feel that way. It’s responsive and easy to change settings and works flawlessly on system startup and never gets in the way when you don’t want it to. You can go in here and tweak sensitivity and polling rate settings as needed. Overall the deathadder v4 retains the comfortable shape of the previous mice while lowering the weight and adding some nice new stuff. I especially like the optical scroll wheel and the overall build quality. The mouse is expensive but also includes the 8000hz receiver in the box instead of being a separate purchase. It’s also very well built for the light weight. For a gamer with a high refresh rate monitor who likes shooters or other fast games and likes the deathadder shape, it’s a great choice.

The Razer DeathAdder V4 Pro is a solid mouse. This is my 3rd mouse of the DeathAdder series, last being a V3 hyperspeed, which boasted being lightweight. The design between these models is similar in look, the V4 Pro is more elongated and a bit heavier, a nice weight sensation in the hand honestly (as hyperspeed was almost too light in my opinion) and fits well while being held. The switch click of right/left click have a well audible sound along with clear feedback to acknowledge the click/command has been entered. The scroll wheel uses optical instead of mechanical design - if scroll VERY slow the scroll command actually happens RIGHT before the mechanical click has occurred, making response/feedback precise to knowing you're moving before the mechanics does. The optical sensor is great, providing up to 45k DPI (if you do anything that requires that level of precision I applaud you) - but overall movement is tight and responsive. The V4 Pro has an atypical dongle, which I find the coolest aspect of this mouse. The dongle is a hemispherical dome which connects to USB by a USB-C cable. The dome is heavier than I expected, having a weighted base - which luckily my cat was not successful with knocking off. She batted at it a couple times but then let it rest as it did not easily move. The dongle is equipped with antenna of greater strength comparatively per Razer's report while also displaying LED indications for multiple aspects of the mouse. Using LED colors the connection status is displayed on the left, battery life in middle and polling rate on the right by dault (as polling rate is a major focus of Razer advertising/design for the V4 Pro) but you may change any of these to be permanently off of DPI stage as well. The DeathAdder V4 Pro, like other Razer products, thrives in the Synapse Environment. It also helped me to know the power button also cycled DPI (it's written there on the bottom of the mouse but I had not noticed at first). Scroll click, the 2 left sided mouse buttons, right click may all be clearly customized with multiple options (macros included) and scroll up/down may be slightly adjusted as well to have different function. Toggled DPI may be changed/set and toggled off, default 5 options but may limit those available. There is ability to change the rotation baseline as well if you happen to hold the mouse slightly from straight up/down. Otherwise, it is advertised to have up to 150 hours of battery life. I personally have not paid attention other than noticing it does not come fully/nearly charged and needed that initial hook-up. Otherwise, having the possibility of an LED indicator light just makes my life easy, when I see red, I plug in before bed. My only wish, for the majority of Razer mouse series, is if LED lighting was incorporated. Even if some snake eye lights or something to add a little flare. But otherwise, happy as expected with the Razer name.

It's rare that I can say that something as mundane as a mouse offers an experience that you can't get anywhere else. There are so many different manufacturers shuffling around the same basic feature set that most are really just competing on tiny matters of build quality and overall aesthetics, so I really wasn't expecting all that much from Razer's latest Deathadder Pro. To my surprise, however, they have managed to produce something that I really don't think you can get anywhere else. It is a niche product, to be sure, but it knows exactly who it's built for and I think will find success with its targeted demographic. The first thing you'll notice after unboxing the mouse is the weight. At 56g the mouse feels almost insubstantial, even more so than a lot of wired mice which don't have to worry about including batteries. Personally I've always viewed ultralight mice, particularly wired ones, with a little skepticism, but in this instance they've gotten the mass low enough to make me a believer. Every twitch of your hand will produce some feedback here, which can be a pretty big deal with today's e-sports titles. If that were all the mouse offered, this could actually end up being a hindrance. But that is far from its only trick. The sensor on this thing is not only hyperbolically precise, it's tunable to a degree that I don't think anything else is. Once you've got the Razer Synapse utility downloaded and installed you can dial in sensitivity to match your exact preferences, allowing adjustments as small as 1DPI, or just let it figure it out based on the title you're currently playing. I'll admit that I'm nowhere near skilled enough or patient enough to calibrate my mouse sensitivity to suit my play style or environment, so letting the software just do it for me was actually pretty nice and made sure I was getting more value from that feature than I usually would. Additionally it allows you to adjust sensitivity for how far the mouse can lift off whatever you're using it on before the sensor stops tracking motion, a feature they refer to as asymmetric cutoff. This is honestly kind of essential for a mouse that's only 56g, as it does tend to lift off a lot more than most other mice I've used, but has a few other less obvious applications too. Specifically I found it helpful when trying to use the mouse on a couch I was sitting on, where the irregular shape and texture of the cushion serving as an impromptu mousepad wasn't the most friendly to the sensor. And you get all this somehow without sacrificing battery life or polling speed. There are a few potential downsides. Perhaps the biggest one for a Razer product is that this is completely lacking in the company's usual over-the-top programmable RGB accents, which I imagine simply draw too much power for whatever microscopic battery drives this thing. Some will probably be thrilled to hear this, but I imagine most of them aren't looking at Razer products in the first place. Second is that connectivity is limited to the wireless puck included with the mouse, which is quite large as dongles go. And since it is built for E-Sports it has a pretty basic scroll wheel and a bare minimum of buttons, making it somewhat less appealing for day-to-day productivity tasks or more casual players that may wish to use the extra buttons for macro assignments. But let's face it - this is not a mouse built for either. This is a device built for E-Sports enthusiasts. And if you count yourself among them, I think the Deathadder v4 Pro is going to be a very tempting piece of gear.
