Review (3/5): okay
as soon as you hold this thing onto the sold of your feet it stops working, therefore you have to hold it lightly above your sole without putting a lot of pressure. making the job of your pedicure a lengthy process. it does not ship with the battery, but overall i must say it does remove the callus, not one time though, u have to do the pedi at least once a wk for like 6 wks. easy to use, takes away all that manual rubbing back and forth with a pedi file.
