Our Verdict
Razer Viper Ultimate
Corsair M65 PRO RGB
The Razer Viper Ultimate is an excellent wireless gaming mouse, while the Corsair M65 PRO RGB is a good, wired gaming mouse. The Razer is significantly lighter, has a more flexible cable, smoother gliding mouse feet, and you can use it wired or wirelessly with its USB receiver. It also has a higher maximum CPI, one additional side button, and significantly lower click latency. Unfortunately, its software is only compatible with Windows. On the other hand, the Corsair is a wired-only mouse, but it feels sturdier, has a more precisely adjustable CPI, and its software is compatible with both Windows and macOS.
