I love this device. I purchased it because it is the brand name that my gym uses in addition to being the one my brother-in-law did all the research for. Best on the market, he says.
Love it! It has helped me loosen up My whole body and relieve tension in my back, back, hips and legs. My job and life require a lot of sitting. This has helped me tremendously combat my body’s response to that. I wish I had this years ago!
