It's a palm sander (5" and 6") from Mirka that is supposed to feel more
like an air sander. It uses a 22V brushless motor with a separate
(quite large) power supply box. The handheld part for the 6" sander
weighs just over 2 pounds and is very compact. The 6" sander is
available with two different orbit sizes.

Looks like it's currently priced between the Festool ETS 150 and the
Rotex 150.
