Keychron K3 Pro, equipped with blue switches, supports wireless and wired connections. I've been using it for about two weeks since I bought it. It's in excellent condition, with no signs of use. It's the white backlight model and does not support hot-swapping. As a bonus, I'll include aftermarket keycaps for a change of appearance. The clicky feel was amazing, but I bought it for work, and the loud sound made me worry about those around me, so I'm selling it. I recommend it for personal use or for those who can use it in an environment where it won't bother others.
