Pros

  • Firmware is in mainline QMK, so the keymap is fully customizable
  • Case files are published openly (plate and high-profile versions)
  • Small 30% split layout keeps hand movement short

Cons

  • DIY build only; no retail sales listed
  • Very few keys, so you have to rely on layers
  • Documentation covers little beyond build commands
