The ion band is described as haveing some health benefit but to get a full benefit you must wear for 30 days. I tried the full 30 days and nothing happened. In fact, I actually felt worse. When I purchased the product, I was provided the Purlife brocheure. When I tried to get a refund, nobody will respond to my e-mail. The health benefit has no merit and based on reviews/reports, from medical professionals, the claims Purlif makes regarding what thei product does for you health wise is junk science.
