The Keychron Mechanical Switch series, Keychron did a great job naming and marketing these haha. These are one of the switches I've been looking at for a while but never got around to buying because they weren't on Keychron's Taobao store, and their main website has the world's worst shipping prices. Keychron Red - it's a red linear from Huano.
