I was skeptical
I was very skeptical at first.  I purchased something similar a few years ago and as soon as it touched my foot it wouldn't spin!  A woman posted a video of this working and so I purchased it.  My heels are horrible.  Massive cracks.  I purchased with this a  callus remover and a new cheese grader for my heels and haven't had to use either of them.  This works so good!  I'm telling everyone to buy it.  I'm highly impressed!
