Pros

  • Thumb trackball lets you move the cursor without leaving the home row
  • Hot-swap sockets for MX-compatible switches; thumb keys can use Kailh Choc low-profile switches
  • Reversible PCBs allow building it with the trackball on the left side
  • Keys on the non-trackball half are arranged close to a numpad

Cons

  • Soldering kit; ProMicros, switches, keycaps and the ball must be bought separately
  • With only 39 keys, many inputs depend on layers
  • Wired only; the halves connect with a TRRS cable
