Review title is Another gadget for the junk pile [SEP] Another gadget for the junk pile. Maybe I can get 5 bucks for it at a garage sale. Difficult to control. Even at the slowest speed it burns hence the need for the fan but no fan is going to cool burning skin. The sanding disk needs to be convex rather than flat. It leaves lines where the edge hits. It would probably be easier to control is someone else was doing it for me as it is difficult to reach the bottoms of my feet but then they wouldn't know when it is burning me. Might as well be using a Dremel tool. I think I’ll stick to the knife I’ve been using.
