Compatible with laptops, iPads, iOS, Windows, Mac, or Android. There is no troublesome connection process, and the wireless connection is quick and stable. You can check the battery level at any time with Fn+Space. A 2.4G wireless receiver and a wired cable are included. Gasket-Mounted Mechanical Keyboard: In addition to the silicone gaskets on the plate, we've added sandwich silicone sound dampers to the plate and a full-fit large bottom silicone pad between the top and bottom cases to provide a better gasket typing experience. This design significantly reduces the gap between the PCBA and the bottom case, avoids the impact of metallic noise, maintains the flexibility of the gasket structure, and improves the overall typing sound. Unique Transparent Design & Technical Compliance Certification: Pursuing ultimate transparency, we have adopted a high-quality transparent polycarbonate keyboard top and bottom case, transparent keycaps, and transparent crystal switches. The keycaps are made of high-quality transparent PC material and use UV-printed keycaps. The entire body is transparent, making the RGB lighting more vibrant and creating a highly visible environment even in dark environments. Hot-Swappable PCB, Compatible with 3Pin/5Pin Switches: Equipped with a hot-swappable PCB, allowing you to freely replace and change switches. Compatible with most 3-pin and 5-pin mechanical switches. Pre-installed with lubricated custom switches that provide an unparalleled tactile response with a lifespan of up to 5 million keystrokes. RGB Backlight & Software Customization: You can freely select up to 9 types of factory-set lights and music rhythm modes from the keyboard. We also provide custom software to design new effects.
