The Razer Viper V4 Pro is a right-handed symmetrical wireless mouse designed for high-precision gaming. It features the Gen-2 Focus Pro optical sensor, which provides a maximum resolution of 50,000 dpi, a tracking speed of 930 ips, and 90 G acceleration to ensure every movement is captured accurately. To minimize input lag, it utilizes Razer HyperSpeed Wireless Gen-2 technology and supports a true 8000 Hz polling rate, though it can also be used as a wired device via its USB connection. Weighing only 49 g in black or 50 g in white, this mouse measures 127.1 x 63.9 x 39.9 mm and is finished with a smooth-touch coating for a comfortable grip. It includes six programmable controls with switches rated for 100 million clicks, allowing for long-term reliability during intense sessions. The integrated battery offers up to 180 hours of use and charges through a USB Type-C interface. For setup and customization, the mouse works with Razer Synapse 4 across Windows, MacOS, and Linux, and can store one profile in its onboard memory. The package includes a specialized hemispherical wireless dongle with a weighted base and a taller antenna to maintain a strong signal, featuring three LED indicators that track battery life, connection status, and the current polling rate.
