Drop, now owned by Corsair, just announced its latest custom mechanical keyboard, the CSTM80. I’ve been testing it for the better part of two weeks to see exactly what it has to offer in comparison to Drop’s other keyboards and the wider keyboard market. As you might have guessed from the name, customization is the name of the game, including a configurable typing experience, magnetically swappable cases, full programmability, and more for only $99 barebones or $149 for the fully built kit.
