Back relief and so much more.
It took a little while for it to get to us as we live in Canada but it arrived the day of stated delivery. This thing is built like a tank, think dog toy Kong it is indestructible. It is hard but has a rubber tire quality that makes it just soft enough you can really dig it into your muscles without discomfort. Absolutely love this thing both the wife and myself are using it daily it is working wonders on my lower back.
