good product for exfoliation and improving circulation [SEP] 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 weeks going through several states even on the east coast poor communication on their end as well like i said not usual for amazon
