Was terribly disappointed at first - A clip fell out on the belt's first rotation. After an hour take-apart, the clip was back in place, and I set out to strip old paint off of a window. I was very impressed. This little unit had some claw, but not too much that I wouldn't use it for some pretty fine work. Held it aloft for 10 to 15 minutes at a time, and never felt the weight. Also didn't see any sawdust because it was all in the bag! The plastic case could be stronger, but then there would have to be other compromises, like weight or price. This sander strikes a fantastic balance for the do-it-yourselver.
