Compact 75% Layout for Desk Space

This 82-key mechanical keyboard uses a 75 percent ANSI layout that saves 30 percent of desk space while keeping the function row and navigation cluster. The gasket-mount structure with a 1.2mm slotted PCB and four sound-absorbing layers creates a softer, more consistent typing feel. Pre-lubed custom linear switches and double-shot PBT pudding keycaps add smooth action and vibrant RGB backlighting.

Suits Wireless Users Wanting a Knob

Ideal for typists and gamers who want tri-mode connectivity with Bluetooth 5.0, 2.4 GHz wireless and USB-C wired options, plus a built-in 3750mAh battery rated for up to 200 hours with backlighting off. The integrated rotary knob and LED power display give quick volume control and battery visibility. Buyers who need a full-size numpad or dedicated macro keys should look elsewhere.

Check Your Setup Before Ordering

Verify you have a free USB-A port for the 2.4 GHz receiver and a USB-C port for wired charging or data. The left Type-C port supports wired mode only, while the additional USB-A and second Type-C ports act as a hub for peripherals. Ensure your operating system supports the programmable driver software for macro and RGB customisation.
