Hot-swappable custom keyboard: Suitable for 3/5-pin mechanical switches (compatible with Cherry MX switches), it comes with a 2-in-1 keycap puller, allowing users to easily replace mechanical switches or keycaps themselves. The pre-lubricated linear red switches reduce friction and spring noise, requiring only 45g of trigger pressure. They offer fast response and effortless operation, and are paired with PBT keycaps. Their lightweight, quiet, and durable feel make them ideal for long typing sessions and e-sports enthusiasts. RGB Backlight: Adjust the light color, brightness, and speed with approximately 16.8 million RGB colors and input VIAL. Choose from 45 preset light modes, including built-in rainbow, breathing, and rhythmic light, to create the perfect ambiance for your typing experience. Easily identify keys even in dark environments. Programmable Keys: All keys are fully programmable. Remap any key via VIAL/QMK and create custom quick access layers to speed up your workflow. With a simple click of the mouse, you can map any key to a different function and create a keyboard layout and function configuration that perfectly suits your needs, improving comfort and efficiency. Wired connectivity: Equipped with a 1.5m USB-C cable and a 28cm TRS cable, the keyboards can be used together or independently. The 40% ultra-compact layout (46 keys) frees up desktop space. The split design allows you to adjust the distance and angle between the left and right keyboards, reducing pressure on the shoulder and wrist joints and reducing shoulder and neck fatigue caused by long-term use.
