The Razer Deathadder is a gaming mouse designed for speed and accuracy, with the ability to change settings on-the-fly. Featuring optical sensors capable of tracking at up to 5 meters per second (150 ips), this mouse will make you feel as though your fingers were attached to lightning bolts. In addition, a comfortable body design allows hours of uninterrupted gameplay without cramping or discomfort.

For well over ten years, the Deathadder brand of the mouse has been a fixture of FPS gaming and has been a big success. With Razer stating that over 10 million units have been sold throughout the series, it’s exciting to see how far the Deathadder Elite has progressed since its release in 2016. With an improved optical sensor, more sensitive optical switches, redesigned shoes (feet), and a modest design refresh, the Razer Deathadder V2 is the brand’s newest advancement on a classic.

It’s been about a year since I reviewed the Deathadder Elite, Mamba, and Basilisk, so I’m looking forward to seeing what the new edition offers.

Size & Weight


The Razer Deathadder V2 has a design that is all too recognizable, but if you haven’t considered it, it is basically on the bigger side of a medium. The V2 is the same length as its predecessor (127mm) but with a smaller grip width (42.7mm) and a slight height decrease of just 1mm.

I’ve always liked right-handed ergonomic mice in the medium and above size range, whether the Zowie EC1-B, Logitech G703, or even the Corsair Glaive; they all fit nicely in my medium-sized hand (180110 mm). The mouse is just long enough for me to rest my palm on when browsing, and the grip width seems custom-made for my particular playstyle (palm/claw), with my ring and pinky resting comfortably on the tapering exterior. The hump on the mouse is still as subtle as it was on the earlier Elite model, and it helps support and soothe my hand.

So, if you’re acclimated to the original Deathadder’s size, the V2’s size won’t take you off guard. The weight, on the other hand, is a different matter.


The model’s weight decrease is one of the primary upgrades from the 2016 Deathadder Elite (96g). Razer has reduced the weight with each version, and the V2 is now 16 grams lighter than its predecessor. The Deathadder V2 weighs the same as the Logitech G Pro wireless at 80 grams.

Now, whether or not a mouse’s weight feels nice is highly subjective, but this is much too light for me. The mouse is still as large as in previous generations, but it now seems hollow due to its weight decrease. My preferred mouse weight is approximately 94-100 grams, but that’s not to say I can’t like a lighter mouse; it just takes a little longer to get accustomed to.

The Deathadder was reasonably simple to maneuver about the mouse pad even when it weighed 148 grams back in 2013, owing to its easy-to-grip design and excellent feet. The improved PTFE strips we see beneath reduce friction and make this seem lighter, letting the V2 speed around even the most abrasive pads.

Shape & Texture


This mouse’s form distinguishes it as a Deathadder, and it has stayed mostly constant for well over a decade. Whether you like Razer or not, this mouse’s secure and pleasant ergonomic form is unquestionably one of the greatest ever produced.

The form supports medium to large hands and may be a touch large for individuals with tiny hands. The V2’s design fits well in my right hand and is comfortable at all times. The curves all softly meld together to make this magnificent design, with the subtle hump providing superb support for my knuckles. The thumb groove at the side buttons is the right shape and size to accommodate my thumb while still allowing me to reach those buttons. The first minor design update may be seen on the right-hand side of the mouse. The form softly slopes down the shell to the front, allowing your fingertips to naturally run into the concave like main buttons.

It had been brought to my attention that a few Deathadder owners had complained about the earlier Deathadder Elite’s flair flickering out, something I had not seen. Razer has decreased this, and the curve on the right now roughly resembles that of the Mamba wireless, despite the fact that it is scarcely discernible.

The matte black coating on the shell has been completely overhauled, with Razer returning to a microtextured finish rather than a smooth one. When compared to the Elite, the new texture is somewhat scratchy to the touch. Although it’s still enjoyable to handle, I prefer the smoother material on the Elite, Mamba, and Basilisk V1.


Regardless of whatever texture I choose, this mouse stays in my palm even when flung about quickly in Counter-Strike: Global Offensive. The side grips have been modified to feel less clunky while being considerably more durable. The Elite’s side grips protruded outwards, making it seem like you were grasping them rather than the mouse itself. All of that has altered though, with the grips feeling like they’re a part of the shell and the micro-dot texture feeling a lot nicer on the fingers.



Since their introduction, one of the key advances with Razer’s new mouse has been the switches underneath the primary buttons. The new and improved optical switches look to be a love-it-or-hate-it proposition, since they are less sharp and tactile than previous generations. However, they are more responsive and obviously more dependable, so the double-click problem we’ve observed in the past should be resolved. For me, the buttons had a strange feel to them at first, but it’s something I could easily get accustomed to for the sake of consistency and performance.

It’s worth mentioning that the 0.2ms difference in actuation time between the switches isn’t visible, but they are quicker and more robust. These optical switches have a lifespan of 70 million clicks, compared to 50 million for the Omron switches we saw in the Deathadder Elite.

Let’s speak about the buttons themselves, since owing to the nature of everything being one shell, there has been the occasional difficulty with post and side travel in the past. While there was a little amount of post-travel in the major buttons, I had to look very hard to see it, and it’s barely visible.

Another difference is Razer’s DPI switching buttons, which are situated right beneath the scroll wheel at the top of the mouse. In an effort to get the buttons out of the way, the shell has been significantly modified to fit them. Even though I’ve never accidently touched the DPI buttons, this is a nice improvement since it eliminates the danger entirely.


The side buttons are just as gratifying as the ones on the Deathadder Elite, with good actuation and no risk of accidental presses. The look and tactile feel of the mouse wheel have been altered by Razer to match the Mamba wireless. The wheel strikes a good mix between silent smooth scrolling and tactile steps, and it’s a significant improvement over the last Deathadder’s.

Finally, much like the Mamba wireless, Razer has incorporated a profile button on the bottom of the mouse. This button was meaningless for me since I use the same mouse for all games, but I suppose it’s great to have alternatives.


The new cable is another another difference from the previous Deathadder. Although the cable on the Elite was adequate for a braided wire, the V2’s Speedflex cable is lighter and more flexible. The cable is Razer’s version of paracords, and it will survive the test of time while also being less noticeable while in use.


The cable is 2.1m long, similar to the Elite, and although the material has improved, you’ll still want to tuck it beneath your keyboard or invest in a bungee. The cable is significantly thicker than earlier models, reminding me of the thick braid on the Logitech G403, so you’ll have to use some power to get it into a bungee.

Sensor & Performance


The changes to the Deathadder V2 don’t stop there; the sensor has been replaced with Razer’s newest Focus+ optical sensor. The previous Elite’s sensor was superb, and it is still recognized as one of the finest available. The Focus+ sensor, which is just a PWM 3399, performed well throughout our tests.

I feel guilty bringing up DPI’s marketing spiel, but this newest Deathadder can now reach dizzying heights of 20,000. Isn’t it fantastic? No, since I’ve never encountered someone who uses more than 1600 characters. While no one who wants to strike a target in-game would ever utilize this much DPI, it is available if necessary.

The sensor tracked well when playing a couple FPS games, with no smoothness or jitter. Furthermore, when I pushed it to its utmost in CS:GO, I didn’t receive any tilt slam (I use low sensitivity and 800 DPI). The V2 has an IPS speed of 650, which means you can swipe over your desk pad at rapid rates while still tracking a target properly. Everything felt precise, similar to the Deathadder Elite, and when a trustworthy sensor is combined with such a fantastic design, you’re in for great gaming pleasure.


Like other Razer mice, Razer Synapse is the software you’ll need to make modifications. DHowever, don’tworry if you don’t like the program since the Deathadder V2 has inbuilt memory. This means you may store all of your mouse settings and remove the app at the same time.

Everything from the polling rate to the lights may be changed in the program. You may also customize your DPI settings and use Razer’s newest LOD technology. Regardless of the surface you choose, the Asymmetric cut-off allows you to select your cut-off point to a suitable distance in millimeters. I didn’t use this since the mouse came with a flawlessly flat surface, but it’s always nice to have these minor alternatives because not everyone has a smooth surface like mine.


An update on a classic might be dangerous, but there’s more to it than a refresh this time. Razer has noticed and made outstanding improvements to the mouse’s appearance and performance. If you can overlook the V2’s small weight and are a fan of the Deathadder, upgrading to this is a no-brainer. This very accurate serpent’s ergonomic design, improved switches, sensor, and cord are just a few reasons to give it a try. Fantastic mouse.
