Good product for exfoliation and improving circulation
This is a simple design-like a rubber belt with small bumps on one side and smaller but denser raised rubber pieces on the other.  Light weight and pliable and easy to use on all parts of the body.  Whether the smaller pieces fall off under use remains to be seen.  My one issue was with shipping.  Took much longer to receive, which is rare for Amazon/UPS, but shipping from Vegas to Phoenix area took 2 weeks, going through several states, even on the East coast-poor communication on their end as well.  Like I said, not usual for Amazon.
