Description

8000 Hz wireless and a battery that lasts months

An 8000 Hz polling rate means the keyboard reports to the computer eight times more often than a typical 1000 Hz model, which cuts input lag in competitive games. With the backlight off the battery lasts up to 660 hours, or about four months at five hours a day. The pre-lubed Silk POM Brown switches are tactile and can be swapped for almost any 3-pin or 5-pin MX-style switch. The RGB backlight can be set key by key.

Who this keyboard is for

Gamers who want the same speed wireless as wired; users who would rather not charge their keyboard often; and typists who value an aluminium case, a double-gasket mount and double-shot KSA-profile PBT keycaps. A system toggle and separate keycaps are included for Mac and Windows, and keys are set up in Keychron Launcher.
