Our Verdict

Razer Viper Mini

Cooler Master MM831

The Razer Viper Mini is an excellent wired ultra-light gaming mouse, while the Cooler Master MM831 is a versatile wireless gaming mouse. The Razer is about half the weight but feels more sturdy, has much better cable and mouse feet, and much lower click latency. Comparatively, the Cooler Master has a much higher maximum CPI, a lower lift-off distance, and extensive RGB, which the Razer lacks. The Razer is best-suited for a fingertip grip for all hand sizes, while the Cooler Master is ideal for a palm or claw grip for nearly all hand sizes.
