A great upgrade from the plastic key puller tool when you frequently remove keycaps. Wires can bend outward to fit onto every key except the spacebar. (The spacebar key can be removed by hand after the surrounding keys are removed). Holds up to 3 keys to speed up key removal. Compatible with with most mechanical keyboards including Cherry MX, others MX Clone (Kailh, Gateron, Greetech, etc), ALPS, and Topre switches. Do not use on "scissor" type switches.
