Our Verdict
Razer Viper Ultimate
DELUX M627
The Razer Viper Ultimate and the DELUX M627 are both wireless gaming mice, but the Razer performs much better. The Razer has a much lighter weight and better quality mouse feet, and you can set a HyperShift button to give you a second layer of custom commands. Also, it has a more precisely adjustable CPI, a lower lift-off distance, and much lower click latency. On the other hand, the DELUX has a modular design and comes with magnetic thumb rests to make the mouse left- or right-handed.
