The smooth, contoured grip on Black & Decker"s Mouse sander/polisher fits snugly in your hand, making this tool remarkably easy to use. The two interchangeable bases are easy to put on and take off (although we had to do it a couple of times to get the hang of it). The iron shaped base is specially designed for larger sanding, scrubbing, and polishing jobs, while the base with a detail tip is perfect for maneuvering in smaller, hard-to-reach areas. The Velcro fastening system makes paper changes quick and easy, saving you both time and frustration. And, because the tip of the sandpaper commonly wears out first, each sheet of sandpaper comes with an extra tab; simply rip the tab off along the perforated lines and use it to replace the tip when it wears out. The Mouse runs at 11,000 orbits per minute, a nice balance between strength and finesse.We tested ours sanding in between chair spindles and were immediately impressed with the smooth (and fast) results. Then we switched bases and put the Mouse to work on larger surfaces; vibration was minimal. The Mouse is easy to control--which is a big plus if you plan to use the tool for long periods of time. It"s a great buy for home hobbyists. In fact, when you get right down to it, your imagination might be the only limit on how many projects this tool can tackle. --Dori Anvinson
