Works great!
It's essentially a velcro-strap waistband with a gel pack inside for heat or cold therapy. I ordered this to replace an old one I had that was no longer usable. This wrap is a quality product, and comes with a gel pack that is much larger than the old one I was using, which is great. You can also place smaller gel packs in the "pocket" if you wish, but so far I've found the larger gel pack that comes with it to be preferable. Works GREAT for lower back pain, gives relief in just a few minutes. Easy to put on and remove as well. There are lots of these for sale here but this one is exceptionally good in my opinion.
