Review title is Mousand Pedi Electronic Pedi Foot File Callus Remover [SEP] I'm a little dissappointed that it stops and starts at its own will. I did the research and this item came with good reviews. I'm sorry, I'd returne it if I could. It's junk. I guess I should have paid a lot more for an electic plug in, but at the time it seemed inconvient.
