Review (4/5): Worth the money
This product worked very well in smoothing out my exceptionally rough calloused feet. The only reason I gave it a four instead of a five is that it wears out the batteries rather quickly and when the batteries run low, it stops spinning with the same force it starts with. I used it 2 times and had to change the batteries, but remember I have very rough calloused feet. Overall I am happy with the product.
