The Viper V3 Pro is Razer's flagship ultralight for competitive play. At roughly 54g it is among the lightest symmetrical mice, with the Focus Pro 35K Gen-2 optical sensor, Gen-3 optical switches rated for 90M clicks and support for HyperPolling up to 8,000Hz (bundled or add-on dongle). Battery life reaches around 95 hours. For fast, flick-heavy shooters it is a benchmark option alongside the Superlight 2.
