Like many other back-pain sufferers, I've dropped a lot of coin on all sorts of medicines, gadgets, etc. and I decided to take a chance on this due to the back pain I get each morning upon awakening. The product itself is ok and does what it says, but just know that this is one of those things that will take some getting used to. Sleeping with something wrapped around your waist all night is not easy to stick with, but I can say that I notice some relief when I first lay down because it keeps my back from sagging down into the mattress. Like a lot of other things - it is hit or miss. I will keep it, but I'm not sure I'll always use it.
