Description

A low profile that is kind to your wrists

Gateron Red is a linear switch: the key travels smoothly with no noticeable bump, which suits fast typing. The low profile keeps the keyboard thin, and three tilt levels help you find a comfortable angle for your wrists. Double-shot PBT keycaps resist oil and the legends do not wear off. Switches can be swapped without soldering, but only Gateron and Keychron low-profile mechanical switches fit. The RGB backlight offers more than 22 effects.

Who this keyboard is for

Office workers and programmers who move between a computer, phone and tablet during the day and want one keyboard for all of them; Mac users, since keycaps for both macOS and Windows are in the box; and gamers who are happy with a 1000 Hz wireless link. QMK firmware and the Keychron Launcher web app let you remap any key and record macros.
