The Logitech G Pro X Superlight finally has competition. Razer’s Viper V2 Pro adheres to a very similar design philosophy as its rival, shedding features like RGB lighting in the interest of keeping the weight down. Interestingly enough, both mice also have incredibly popular predecessors that arguably packed more features like ambidextrous side buttons, but something has got to go when you’re aiming to make the lightest mouse you can.
