The Razer Viper V2 Pro is an ultra-lightweight, wireless gaming mouse that continues Razer's popular Viper lineup. It has the same symmetrical shape but incorporates major design changes and improvements over the Razer Viper Ultimate. Razer has significantly reduced the weight of this mouse; however, they've accomplished this in part by removing several features of the previous generations, including side grips, RGB lighting, and ambidextrous controls. Besides weight changes, this mouse also has a new Razer Focus Pro 30K sensor and uses a new generation of optical switches. Razer also indicates they've improved battery life and wireless performance.
Note: We've received feedback from users reporting that they have received this mouse with a defective wireless receiver. We've included more details about this issue in the Wireless Versatility section below.

Popular Mouse Comparisons
The Razer Viper V2 Pro is a continuation of Razer's popular Viper lineup. It features several improvements, including a brand new sensor, a new generation of optical switches, and a significantly lighter weight than their previous flagship model, the Razer Viper Ultimate. However, this weight saving comes at the cost of several features that characterized earlier generations of this mouse, including the RGB lighting, rubberized side grips, and an optional charging dock. This mouse only has a pair of side buttons on the left, while the Razer Viper Ultimate and Razer Viper 8KHz featured buttons on either side, making them popular options for left-handed users. Overall, this mouse is a high-performance option that competes directly with similar flagship models like the Logitech G PRO X SUPERLIGHT. However, given its reduced feature set and premium price point, it won't be a perfect fit for everyone.
