The Razer Viper V4 Pro is Razer's latest flagship wireless esports mouse, packing cutting-edge tech into a lightweight, ambidextrous beast. At just 49g, this thing is featherlight and built for speed, perfect for competitive gamers who demand maximum agility. The Focus Pro 50K optical sensor (Gen-3) is absolutely insane—50,000 DPI max with a ridiculous 930 IPS tracking speed and 90G acceleration means this sensor can handle literally anything you throw at it. Razer's Gen-4 optical mouse switches fire instantly with zero debounce delay and are built to last millions of clicks without developing double-click issues. The HyperSpeed Wireless Gen-2 tech with 8K polling rate (8000Hz) on both wired and wireless modes delivers near-zero latency—you're getting tournament-level responsiveness wirelessly. Battery life is solid: 180 hours at 1000Hz or 45 hours when you crank it to 8000Hz. The 24-step optical encoder provides precise, tactile scroll wheel feedback, and 100% PTFE feet ensure buttery smooth gliding. With 6 programmable buttons, 1 onboard profile, and deep Razer Synapse integration, customization is endless. Available in black or white with a smooth matte coating and symmetrical right-handed shape, the Viper V4 Pro is built for esports domination.
