This Review Title is Worth the money and the content is: 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..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
