Fully Modular Keyboard: The GMMK's hot swap switch sockets allow you to plug in and out switches according to your DIY preferences, making it the first Hot Swap RGB gaming keyboard. Features include 16.8 million RGB per key, complete customization with our GMMK software, and the ability to directly set major RGB patterns from keyboard hotkeys without the need for software. Excellent Ergonomics and Compatibility: This GMMK kit includes OEM-sculpted keycaps to keep your hand joints and fingers from stiffening over time and preserve their jelly-like texture. GMK works with a variety of operating systems, including Windows, Mac, and consoles that support keyboards (PS4, PS5, XBOX).
