I don't really have very bad lower back pain. It seemed to give pain relief while using it. Then when you take it off you go back to it a little. Seems like it does what it says. May leave some temporary marks on your skin which will go away quickly. Overall a good product. Exactly as described does what it proclaim. You can also stretch in order to decompress your back, but hard to hold that for a while. This is more convenient.
