Razer Viper V3 Pro Review
Aside from the bringing the shape of the Viper V3 Hyperspeed to the Pro series, the 54 g Viper V3 Pro also debuts Razer's latest Focus Pro 35K Gen-2 sensor, and includes the 8K wireless dongle by default. The main buttons are still outfitted with Razer's Optical Switches Gen-3, and up to 95 hours of battery life are cited.
