BLACK+DECKER BDCMS20B 20V Cordless Mouse Sander - Lightweight Electric Hand Sander with 12-Piece Sandpaper Set - Perfect for Woodworking, Furniture Refinishing & DIY Home Projects

I love B&D cordless tools and I have several (drill, impact drill, weed trimmer) that all work with B&D's 20V Lithium Ion batteries. That said, I have several of these batteries and chargers, so I was thrilled to see that I could purchase a B&D sander that was without the battery, and cheaper for that reason.The sander is lightweight even with the battery. In fact, the battery adds a bit of balance to the tool and overall is very easy & comfortable to use. It comes with a "finger attachment" for corner, edge work and fine detail use. It also has a dust-collection bag that is easily removed for emptying, which should be done after every 5-10 minutes of wood sanding. (The bag should not be used for metal sanding, and a face mask or respirator is recommended in that case.) The tool also comes with two 120-grit B&D sanding sheets to get you started that are easily attached (hook & loop style) to the sander base. I would estimate the battery life to be about 30-40 minutes of continuous use, but with start/stop techniques, probably an hour or more. It has a conveniently located start-stop switch on the top of the handle.I used it today to begin sanding off old worn paint from our two Adirondack chairs so I can change their color. It was quick and easy. The vacuum feature worked great, leaving only minimal dust on the chair surfaces. I also tried it to remove rust from an old charcoal/smoker grill that we have and are converting to a planter. On the flat surfaces, it didn't do as well as on the chairs (hello naval jelly), but it did better on the rounder handles, etc. I love this tool and the convenience of cord-free operation and its easy maneuverability.ONE NOTE OF CAUTION: In order for the vacuum function to work properly, you must have 12-hole sanding pads that fit the intake holes of the sander. I made the mistake of not knowing the toll-pad hole configuration, and I ordered extra pads with the sander. Those needed to be returned and I ordered others that fit properly. If you don't do this, the vacuum mechanism will NOT work properly. Black & Decker offers replacement pads but, while of a superior quality, are very expensive. I recommend 12-hole pads by Lot Fancy that are sold on Amazon. While they do not last as long, they are pretty inexpensive at about $13/50.
