TOUCH Beauty Electric Pedicure tool Foot File Callus Shaver Wet Dry Rechargeable Corn Hard Skin Remover with Roller Head TB-1536. I bought this for my wife as she lost the cord for her other one. This on though uses a USB micro charging cord so she will never be without it again. It charges fully and lasts a long time. It's fast and efficient while taking care of her calloused rough feet without hurting her. The on/off button is located on the top while the dry skin residue is directed away from the switch to the bottom side. This should mke this item last and work much longer that any others I have seen. Incredibly well designed for years of use. She loves it and I do too because it's the last one I will ever have to buy her!
