Razer Inc. announced the launch of the Viper V4 Pro wireless gaming mouse and the Gigantus V2 Pro mouse pad in April 2026 [1, 2].
This release targets the competitive esports market by prioritizing extreme weight reduction and sensor precision to give professional gamers a technical advantage.
The Viper V4 Pro utilizes HyperSpeed Wireless Gen-2 technology to ensure ultra-low latency during high-stakes gameplay [3]. This hardware allows the device to maintain a high level of responsiveness while offering a battery life of up to 180 hours [3].
Physical weight is a primary focus for the new model. The Viper V4 Pro weighs 49g [4], which places it among the lightest competitive mice currently available on the market. This reduction in mass is intended to reduce wrist fatigue and increase flick-shot speed for users.
Under the hood, the mouse is equipped with a sensor capable of reaching 50,000 DPI [3]. This high sensitivity allows for minute adjustments in cursor movement, a critical feature for pro-level play.
Despite the internal upgrades, the exterior remains familiar. A reviewer from MobileSyrup said, "At a glance, you probably wouldn't be able to tell Razer's new Viper V4 Pro mouse apart from the Viper V3 Hyperspeed and V3 Pro" [5].
The launch includes the Gigantus V2 Pro mouse pad, designed to complement the Viper V4 Pro's sensor, and glide characteristics [1, 2]. Razer said the goal of the new gear is to provide a lighter, higher-DPI wireless experience for those competing at the highest levels of gaming [6, 7].
“The Viper V4 Pro weighs just 49g, making it one of the lightest competitive mice on the market.”
The Viper V4 Pro represents the ongoing industry trend of 'weight stripping' in gaming peripherals. By pushing the weight down to 49g while increasing DPI to 50,000, Razer is attempting to capture the niche market of professional esports athletes who prioritize raw performance and physical agility over feature-heavy multi-purpose mice.
