If you have never used one of these, just want to report that they really do a good job. Not a big fan of Black and Decker tools, as I have found that they are usually a little under par. However, I had some louvered interior doors to do, and just no way to do much of a job sanding them by hand, or with any other little sander I have found that was reasonably priced. Since I only had a fairly small amount to do, figured why not. The thing may not last long, but if it finishes the intended job, will be well worth the money. Amazing how tight of a corner it will get into. Would not recommend it for big jobs, but for smaller jobs they are worth the bucks.
