We previously incorrectly stated that this mouse works on glass when, in fact, it doesn't. The review has been updated to reflect this change. The mouse blitzes through the portal, moving at such speed that it transforms into a green bolt of energy. The mouse’s sensor is designed to work on a variety of surfaces, including glass. I tested the mouse on everything from mousepads to mirrors to the side of my French Bulldog, and it worked on everything (including transparent glass and plastic), except the mirrors. On the V3, the thumb indentation on the left side of the shell is less pronounced, the flare on the front of the mouse (giving the V2 and its predecessors that almost trademark ‘trapezoid shape’ at the front) has been dramatically reduced, the hump sits a little higher (as does the scroll wheel and the side buttons), and the V3 also feels more slanted due to the fact that the highest point of the hump has been moved towards the left, whereas it was slightly more centralized on earlier versions. It’s kind of varied for me, and it’s also quite difficult to answer since I use so many mice over the course of a year it’s hard to kind of ‘settle’ on one as my main (I really like to thoroughly test mice).

We open on a dark void, where a ray of light traces across the side silhouette of a mouse, subtly revealing its bold red design. I see the DeathAdder (and especially this newer one) as a claw and palm grip mouse for people with medium to large hands. With these shape changes you can get by with smaller hands, but due to the size of the mouse it might become unwieldy for making smaller adjustments. Fingertip grippers can glance at this one a little longer as the separated buttons mean that it lends itself to that style of grip a little bit more, but there are a ton of other options out there that I would recommend before trying out the DeathAdder if you’re using a fingertip grip, with Razer’s own Viper line as an example.

Troubleshooting

The screen glitches as the mouse now rests atop a high-tech weighing scale in a white futuristic lab. We've converted this review to Test Bench 1.4. This update modifies our Hand Size Recommendation test, adding a more granular hand size recommendation chart. We've moved several minor tests into different test groups, removed the Travel usage, and added a new Raw Performance usage. For more details, you can see our full changelog here. I thought I’d find the bottom-based DPI switch to be inconvenient. But the truth is, I find most top-based DPI switches to be inconvenient, anyway. And the DeathAdder V3 Pro is so lightweight and easy to hold that the DPI switch didn’t end up being very inconvenient at all.

The DeathAdder V3 Pro is a solid piece of equipment. Shaking or tapping it revealed no noises, and I couldn’t get it to bend or squeak when applying pressure all over the mouse. It’s very impressive to me how Razer has managed to make such a strong mouse at such a light weight. Ultralight mice have a tendency to feel a bit flimsy at times due to their weight and the shell construction designs that are necessary to achieve that weight, but I didn’t get that feeling here at all. This is one of the more premium feeling mice I’ve tested in a while. Another noteworthy change can be seen on the sides of the mouse: Razer has ditched the integrated side grips and went for custom-cut side grips that you can apply yourself, much like with the Viper V2 Pro.

We've added a link to the newly-reviewed ASUS ROG Harpe Ace Aim Lab Edition in the Wireless Versatility section of this review. A greenish-blue light turns on as all the prototypes become holographic, save for one in the center. As impressive as the changes under the hood are, I was personally more curious about the change in shape, and that’s something that immediately catches the eye. Gone are the signature deep comfort grooves on the buttons, for example. This new DeathAdder looks and feels very different from its predecessor, so if you were expecting minimal changes you better adjust those expectations, as this is definitely a rather big change. I will talk about the shape further down in the review but I wanted to touch on it since this is of course one of the first things one notices about this new mouse.
