This Review Title is Not thrilled and the content is: If you have very delicate feet or very thin calluses this is okay. I have thick calluses and tough skin and every time you put any pressure on this thing, it slows down or stops. Also, the design can catch your skin! I took the top piece off and it was better (and didn't catch my skin). All in all, for the price it's just okay..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.
