Our Verdict
Razer Viper V3 Pro
Pulsar X2 CrazyLight
The Pulsar X2 CrazyLight and the Razer Viper V3 Pro are both lightweight wireless gaming mice aimed at competitive FPS players. Both deliver outstanding raw performance, and their symmetrical shapes make them well-suited for a claw or fingertip grip for small or medium-sized hands. The Pulsar is smaller and noticeably lighter. It also has a wider range of colorways available. The Razer, on the other hand, is slightly larger, especially in length. It has a solid baseplate design that protects the internals from dust and debris
