This is a really great product for relieving muscle tension. I purchased it with relieving back muscle tension in mind but have discovered how versatile and effective it is in dealing with tightness in other parts of the body. In the short time I have it I’ve found it enormously beneficial. I’m 52 and a keen golfer. I use it before and after games and practice. The Back Baller is sturdy and well thought out in it’s construction. I would highly recommend it for sports people and non-sports people alike.
