Review on 🦶 Blue Portable Electric Foot Grinder Electronic Foot File Pedicure Tools - Callus Remover Feet Care Sander with 12 Replacement Grind Heads for Cracked Heels & Dead Hard Dry Skin by Christine Jensen

"Dry sander for feet/calls”. Not for use on damp skin or wet calluses. Not a professional tool. what).(why 4 stars) >>> What I didn't expect.The first time I used it, after "two minutes" of use, the motor jammed and blocked, although I had kept it clean. He doesn't like over-pressure, so where he has no choice but to "experiment", find out what pressure is right when using the tool. (I disassembled it to see why it is sticking. It does work, the gearing is plastic and well lubricated, but not all parts are lubricated. When I sprayed the unlubricated parts with silicone spray, e.g. around the Head around where the grinding wheel is attached and in the area of the shaft this seemed to work much better as that area has plastic spinning against plastic quickly with no lubrication, no bearings at all.) Grinds dry skin very well, uses 2 grinding wheels supplied. Easily removed and replaced. Comes with a small cleaning brush and a USB cable for 5 volt operation directly from a charger or USB power source. Otherwise 4 AAA batteries (not included) are used. The lack of a carrying case and being kept in the product box doesn't contribute to the best overall daily use. Suggest customer buy their own tote bag if traveling with one.
