I've been using something similar for years, it came in a kit with a Dremel Contuor sander that burned up on me and they quit making and servicing them,but they make an adapter to fit my Rockler Sonic Crafter and similar multi tools, and Dremel gave it to me for free witch would of never happened with out going there in person and talking to them. They have mini sanding belts for them or you can easily make your own, not sure if there still available, I do usually use them by hand to do my edges.
