Our Verdict

Razer Viper Mini

XTRFY M42

The XTRFY M42 and the Razer Viper Mini are both wired, ultra-light gaming mice. The XTRFY has a lower lift-off distance and a wider CPI range; however, it has no companion software, and it only has eight CPI presets that you can switch between directly on the mouse. The Razer has substantially better click latency, and though it doesn't have as wide of a CPI range, you can set the CPI much more precisely thanks to its companion software that also allows for button customization, sensor adjustments, and lighting profiles.
