Our Verdict
Razer Viper 8KHz
Keychron M1
The Razer Viper 8KHz and the Keychron M1 are comparable wired gaming mice, but the Razer is a better choice for gaming overall. The Razer feels sturdier and has higher-quality mouse feet that glide more smoothly. It also has a significantly lower click latency, a higher maximum CPI, a CPI you can adjust more precisely, and a higher maximum polling rate of 8000Hz. On the other hand, the Keychron has a higher quality, detachable paracord-like cable, and its software is compatible with Windows and macOS. The Razer software is only compatible with Windows.
