The G203 Lightsync places the highest emphasis on speed and precision. With 1000 reports per second, it ensures that even fast movements are captured accurately and keystrokes are executed with virtually no delay. The optimized key spring tension provides consistent clicking with minimal effort. The Lightsync RGB lighting allows you to choose from stunning animations with 16.8 million colors. The six buttons can be freely programmed using the Logitech Gaming Software.

Particularly convenient is the DPI selection button: Set four custom DPI values between 200 and 8000 DPI in the software for your preferred mouse sensitivities and switch between them at any time with a click, depending on whether you need more precision or speed—without the hassle of going through Windows or game mouse settings. The configured settings for button assignments, DPI values, etc., are stored in the mouse's memory.
