It is very helpful for my lower back. I do have to say that when I first put it on, it was a bit hard to get as tight as I liked. The first band you secure together is not elastic and it's why I can't get it to be as tight as I like. I was able to put it on and get the elastic bands to make it tighter. Otherwise, after using the brace for a bit longer than a week or two, I am happy to say it helps to keep my back from giving out.
