Razer Viper V4 Pro review - my new favorite gaming mouse, despite the noise

The Razer Viper V4 Pro is a lighter, tougher upgrade over the V3 Pro, with noticeably better battery life.

Its Focus Pro 50K Gen-3 sensor and HyperSpeed Wireless Gen-2 deliver top-tier esports-grade performance.

The mouse stands out as a best-in-class competitive wireless option, but it remains expensive and its charging cable is awkward for wired use.
