Made of 5052 aluminum-magnesium alloy, the G513 was built to provide a minimal, sleek design in a sturdy, non-slip chassis. Using GX Blue, you'll have audible and tactile feedback for that traditional clicky switch. There is also a detachable memory foam palm rest that is waterproof and sweat-resistant so you can wipe it clean. LIGHTSYNC allows you to customize the G513 with approximately 16.8 million colors along with different animations and effects. You can also sync with other Logitech devices with LIGHTSYNC for a uniform setup look.
