Razer DeathAdder V4 Pro Review
Specifications
Packaging
Shape & Size
The Razer DeathAdder V4 Pro is a large ergonomic mouse at 128 × 68 × 44 mm. The left side has a slight inward curve, the right has a slight outward curve. The front flares slightly outward, and the hump is centered. The shape matches the previous DeathAdder V3 and V3 Pro.
I don't often palm grip due to my larger hands (20.5 × 10.5 cm). I typically use fingertip on smaller mice and claw on medium-to-large ones. On the DeathAdder V4 Pro, I use palm, and it fits my hand and grip style incredibly well. I can claw grip it too, but for fingertip it's too large and likely not what Razer intended for this shape.
Generally, I prefer smaller mice as they give me more control. Larger mice like the DeathAdder V4 Pro aren't usually my pick, but I really enjoy this one despite it being quite different from what I'm used to. My aim is very good and consistent on it and I intend to use this as one of my main mice for a while.
Coating & Grip-Tape
The coating is great—very grippy and makes the mouse easy to reposition quickly without adjusting my grip. It stays consistent even with changes in temperature and humidity. The coating does not seem to pick up fingerprints and skin-oils as fast as many other mice do that also has this type of coating applied to them.
Pre-cut grip tapes for the main buttons and sides are also included in the packaging, but I didn't use them as I find the coating alone provides a solid grip.
Build Quality
Build quality is also great. It feels incredibly solid and I can't make the shell creak or flex, even under heavy pressure. There are no rattles when shaking the mouse.
Weight
The DeathAdder V4 Pro weighs 56 grams. Compared to many new releases, that's higher, but most ultra-light mice are smaller and often have holes in the shell. This is a large ergonomic mouse, and few in this category achieve such a low weight without cutting corners on build quality or using cutouts in the shell.
The weight in relation to its size and shape feels incredibly low and well balanced. Ultra-low weight matters more for me when I fingertip, but since I palm this one, it still feels effortless to move.
Skates
It comes with two large white PTFE skates and a sensor ring. The glide was instantly smooth with no break-in needed. The skates are thick enough that softer mousepads didn't cause the base to scrape, which can happen when skates are too thin.
Buttons
The DeathAdder V4 Pro uses the brand-new Razer Optical Mouse Switches Gen-4, rated for 100 million clicks and are currently only available on this mouse and the Razer Cobra HyperSpeed. Razer says they're 12% lighter with a crisper feel. In use, they're a noticeable upgrade compared to previous generations. They are lighter and more tactile than the previous gen, making them better for spam clicking and providing clearer feedback.
There's no noticeable pre- or post-travel and no side-to-side wobble on the main or side buttons.
Scroll Wheel
The new Razer Optical Scroll Wheel used on this mouse is, according to Razer, 3.3x more reliable than mechanical designs. It feels "softer" and requires less force. Steps are slightly less defined than some wheels but still clear, and it's easier to scroll rapidly. I prefer a bit more definition, but overall it feels great, especially considering the reliability improvements.
Sensor & Performance
The DeathAdder V4 Pro uses the new Razer Focus Pro 45K sensor, developed with PixArt. It's not just a PAW3950 rebrand, but seems to be an entirely new sensor based on its specifications and features. Max DPI increases from 30K to 45K, tracking speed from 750 to 900 IPS, and acceleration from 50G to 85G.
I can't personally feel a performance jump over PAW3950 mice, but I'm also not a pro player who relies on that edge. Still, the improvements are welcome. Even if most won't notice huge differences, it's reassuring that hardware keeps getting more accurate. This also pushes the market forward and raises the baseline. Even budget mice now ship with top-tier specs and I don't believe this would be the case had brands like Razer not pushed the limits on performance.
Conclusion
The Razer DeathAdder V4 Pro costs $169.99. It's pricey, but also the highest-performing mouse in all technical aspects. From its sturdy build and low weight to a proven shape loved by many, there's a lot to like. The optical switches feel fantastic, the new scroll wheel adds reliability, and the sensor pushes new limits in performance.
The price is high, and alternatives offer similar real-world performance for a lower price. If you want the same shape and size at a lower cost, the older V3 Pro is still a great buy, and there are other budget options with inspired shapes too. Still, this mouse sets a new standard that I believe will lift the market. If you have the budget and want top performance right now, the Razer DeathAdder V4 Pro is the best mouse available.
