I was so excited about my Black&Decker Mouse. I thought I'd be able to tackle my difficult sanding jobs. I thought it would do more than it does, and I'm dissapointed that there's only 3 grades of sandpaper. It was billed as a sander and it's more of a fine tuner or a polisher/scrubber. It doesn't sand very well. They need a wider range of grit for a lesser cost, such as 50 grit. I feel like I was ripped off. It's a glorified polisher that can get into the nooks.
