I have one I got at a great discount as a new rep a couple years ago. Only wore it once for a couple hours around the house. There were way too many hooks down below to chance wearing out for a long period of time. I believe the purpose of it is to replace the body organs to ideal positions for optimal digestive function.
If I were to choose again, I would pick a less constricting product. Right now I'm wearing about a 12 inch adjustable band around my midsection a few hours a day just to kinda hold things together and give me lumbar support.
