My wife loves this callus remover. I got her a callus remover rock and she was using that, but this is simply much better solution. It has a built in battery that is rechargeable. Usually it lasts about 3-4 uses for my wife. Comes with its own USB charging cable. There are two rollers, one is fine and one is coarse. Make sure to change out appropriately. The only thing I'd like this thing to do is to make it water safe, which it isn't. My wife likes to clean her callus in the shower.
I HAD RECEIVED THE ITEM FOR FREE/AT A DISCOUNT IN EXCHANGE FOR AN UNBIASED HONEST FEEDBACK.
