Our Verdict

Razer Viper Ultimate

ASUS ROG Keris Wireless

The Razer Viper Ultimate is a better wireless gaming mouse than the ASUS ROG Keris Wireless. It's lighter and has mouse feet that glide more smoothly. It also has a wider CPI range, a more precisely adjustable CPI, a lower lift-off distance, somewhat better click latency, and two extra side buttons on the right side. Comparatively, the ASUS feels sturdier and has Bluetooth support, which the Razer lacks. It also has hot-swappable left and right-click switches.
