Very effective, but terrible battery
This came as promised, and I was happy when I opened it up. It has three barrels all together, with two different amounts of grit. The directions said to charge it for 8 hours before use, and that the light would turn green. When I plugged it in, the light was already green, which was a fun surprise.<br /><br />This little machine is pretty powerful, and I love that it has 180° of use around the top, so I don't have to worry about flipping it around my foot.<br /><br />My biggest problem with it is that it will only run for less than five minutes before it slows down to the point of it being unusable. I love that it's rechargable, because I don't have to flip out batteries again and again, but the very short life off the cord is a major drawback for me.
