Our verdict

A lightweight, high polling rate mouse built for competitive play, with the fastest 8000Hz mode trading battery life for the lowest latency, and cosmetic Niko branding on top of otherwise standard DeathAdder V4 Pro hardware.

Overview

Razer's DeathAdder V4 Pro is a 57 gram wireless esports mouse built around an 8000Hz polling rate and a 45K DPI optical sensor for competitive shooter and esports play.

The headline spec is polling rate rather than DPI, since most players never need anywhere near 45K DPI in practice, but a stable 8000Hz connection reduces the gap between a physical mouse movement and what shows on screen. This Niko edition adds a flame graphic tied to a named CS player rather than changing the mouse's internals, so buyers picking it for the look should know the panels are cosmetic. Battery life splits sharply by polling rate, running far longer at 1000Hz than at the full 8000Hz mode.

Who it's for

Competitive FPS players who already play at high sensitivity and high refresh rates get the most from the 8000Hz mode. Casual or productivity users will not notice a difference over a standard wireless mouse and are paying for headroom they will not use. Fans of the Niko esports branding get a cosmetic edition of the same hardware as the standard V4 Pro.

Pros and cons

Pros

57 gram body suited to fast wrist movement
8000Hz polling rate for competitive latency
Optical switches rated for over 100 million clicks

Cons

Battery life drops to about 22 hours at full 8000Hz polling
Niko edition graphics add cost without changing performance

Performance notes

Battery life is the clearest tradeoff in this mouse: up to 150 hours at a 1000Hz polling rate but only about 22 hours once the full 8000Hz mode is switched on, so competitive players chasing the lowest latency will be charging it more often. The optical switches and optical scroll wheel are built to resist the wear that mechanical parts show over time, which matters more for players clicking at high volume than for casual use. At 57 grams the mouse favors quick wrist flicks over the heavier, more planted feel some players prefer.
