My Egg Shaped Cheese Graters Are Retired!
I purchased the set that came with the Amope Foot File, 3 regular heads, the charger and a nice cosmetic type bag to store it all in.  Cordless is so convenient. It has an on/off and two speed buttons.  Perfect for use in the shower or anywhere else.  The noise level is minimal, so it's not annoying to use.  I have a couple thick calluses on the underside of my heels. They are no match for the Amope Foot File.
