Build macros, and set up per-key lighting and effects. ?High-Quality Transparent PC Material with UV Printing Keycaps? Pursuing ultimate transparency, the X75 takes prime PC material to mold the keycaps and print the characters through a digital printing process. The rigorous production ensures the keycaps survive wear-resistant and scratch-resistant tests. The keycap set is designed with an ASA profile for those who feel like sculpt-shaped keys and an ergonomic typing experience, with different heights in different rows. ?Hot Swappable PCB, Compatible with 3Pin/5Pin Switch?X75 is equipped with hot-swappable PCB to ensure free replacement or change of switches. It is compatible with most 3-pin and 5-pin mechanical switches. Pre-installed the pre-lubed custom switches providing unrivaled tactile responsiveness with up to 50 million keystroke lifespan. ?Unique Transparent Design?Pursuing ultimate transparency, the X75 takes a high-quality transparent polycarbonate keyboard top and buttom case, clear keycaps, and transparent crystal switches. The whole body is transparent, making the RGB lighting more gorgeous, creating a visible environment even under dark conditions. ?Gasket Mounted Mechanical Keyboard?As to give a better Gasket typing experience, in addition to the silicone gaskets on the plates, the X75 adds sandwich silicone sound dampeners to the plate and fully-fitted large bottom silicone pad between the top and bottom cases. This design significantly reduces the gap between the PCBA and bottom case, avoids the noise of the impacted metals, maintains the flexibility of the gasket structure, and improves the overall typing sound.
