Logitech G worked together with eSports athletes to create the Pro Gaming Mouse. This Logitech G mouse is inspired by the classic, simple construction of the Logitech G100 and G100s body made popular by top competitive eSports professionals. Our best optical sensor, PMW3366, provides exceptional tracking accuracy. The metal spring tensioning system delivers the reliable click performance required for high-level competitive gaming. Customizable with up to 16.8 million lighting colors, G Pro also has 6 programmable buttons and an onboard memory so you can setup and save custom commands for your favorite games directly to the mouse. Built on over 30 years of Logitech expertise in mouse engineering, building and testing, Pro is designed for performance play.
