Our Verdict
Razer Viper Mini Signature Edition
Keychron M4
The Keychron M4 and the Razer Viper Mini Signature Edition are lightweight wireless gaming mice. The Keychron has a very small shape that's designed exclusively for fingertip grip. In contrast, the Razer has a much more conventional shape but employs an exoskeleton-like magnesium shell designed to save weight. Both mice have excellent performance, but the Razer has a higher maximum polling rate of 8000Hz compared to the Keychron's 4000Hz maximum, contributing to its better overall raw performance.
