Why people pick it

  • Three ways to connect: 2.4GHz receiver, Bluetooth or USB-C cable
  • Low-profile switches in a slim 75% layout that fits a laptop bag
  • Mac and Windows keycaps included
  • Keys can be remapped in the Keychron Launcher web app

Know before you buy

  • The 2.4GHz receiver takes a USB port, so a USB-C-only laptop may need an adapter or hub; Bluetooth avoids that
  • Battery life drops with the backlight on
  • No Touch ID or fingerprint reader
