Our Verdict

Razer DeathAdder V2

Cooler Master MM831

The Razer DeathAdder V2 is a better FPS gaming mouse than the Cooler Master MM831. The Razer is significantly lighter, has a much more flexible cable and mouse feet that glide more smoothly. It also has a more precisely adjustable CPI and a much lower click latency. Comparatively, you can use the Cooler Master either wired or wirelessly with its USB receiver or via Bluetooth. Both mice are well-suited for all grip types, but the Razer is best-suited for a palm grip, while the Cooler Master is best-suited for a claw grip.
