This is the second 3 D Sander that I've owned.. When it works.. it's great.
However, don't drop this sander on the ground. Something happens to it and the RPM drops to an idle and will not pick up speed, ever. At the idle speed, the housing heats up and stops. you have to wait till it cools down to operate it again.
Craftsman 0.5 amp 3D Sander is recommended by brodie
