Unlike other keyboards, Massdrop’s CTRL mechanical keyboard boasts a hot-swappable board, which means it comes with a full set of switches, but users can switch them out with any MX-style switch of their choice. Plus, it has per-key RGB lighting using SMD components on the circuit board, enabling your switch choice to take advantage of that.
