Designed for eSports athletes, this gaming mouse features Logitech’s most accurate optical gaming sensor, a metal spring button tensioning system, onboard memory for driver-free operation on tournament systems, and a comfortable, durable yet lightweight design. The mouse is optimized to reduce weight to improve comfort, stability and responsiveness. The top surface of the Logitech G Pro gaming mouse is treated with a special coating to improve durability and grip, and the left and right buttons are tested to exceed 20 million clicks ˗ the equivalent of a pro gamer training ten hours every day for two years.
