Our Verdict
Razer Viper
ROCCAT Kone Pro
The Razer Viper and the ROCCAT Kone Pro are both excellent lightweight gaming mice and are nearly the same weight, though the ROCCAT is marginally lighter. The ROCCAT also feels sturdier, has a more flexible cable, and has smoother gliding feet. It also has onboard memory. Comparatively, the Razer Viper has two extra side buttons on the right side, making it a true ambidextrous mouse. Both mice are suitable for all grip types and nearly all hand sizes, though the Razer is best-suited for a claw or fingertip grip, and the ROCCAT is best-suited for a palm or claw grip.
