Keychron K1 Wireless Mechanical Keyboard - Full-size keyboard (100% layout) - Red switches (smooth and consistent typing feel) - US layout - Wired connection (USB-C), Bluetooth - Compatible with Windows and Mac - Contents: As shown in the attached photos - Keycaps have been removed and the caps and body have been cleaned, but please refrain from purchasing if you are concerned. Used for 1-2 years, with no problems at all. I've decided to sell this red switch keyboard because I wanted to try switches other than red switches and bought a new keyboard.
