The G203 Lightsync places the highest importance 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 a consistent click 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: In the software, you can set four custom DPI values between 200 and 8000 DPI for your preferred mouse sensitivities and switch between them with a click at any time, depending on whether you need more precision or speed - all without the hassle of going through the Windows or game mouse settings. The configured settings for button assignments, DPI values, etc., are stored in the mouse's memory.
