Razer Viper V4 Pro - Wireless Gaming Mouse

The Razer Viper V4 Pro Wireless Gaming Mouse is engineered for elite esports performance, combining next-generation responsiveness with advanced optical technologies to deliver consistent precision in high-stakes matches. As the successor to one of the most competition-proven Viper designs, it features upgrades for faster and more reliable input delivery across competitive environments.

With support for a true 8000 Hz polling rate, ultra-low motion latency, and improved wireless efficiency, you can expect stable, dependable performance when every millisecond matters. Professional-grade accuracy is powered by the Focus Pro 50K Optical Sensor Gen-3, paired with optical switching and an optical scroll wheel designed for durability and speed.

The refined right-handed symmetrical shape helps maintain familiar control while the ultra-lightweight design supports quick flicks and smooth tracking across multiple grip styles.

Stay in the game longer with up to 180 hours of battery life (based on 1000 Hz usage). Fine-tune your setup using Razer Synapse, where you can adjust DPI sensitivity, lift-off distance, polling rates, and surface calibration for precise competitive tuning.
