This is the BEST muscle hook - you will not find a better one. Trust me, I tried.
I first encountered one of these in Target, and wanted one ever since. I resisted buying it for a long time because I felt that it was expensive, but I could not find an equivalent product that worked as well. I finally broke down and just bought the damn thing. It helps me massage and ease painful spots on my back that I can't reach myself, and it works much better than the tennis ball technique that my physical therapist showed me. I keep it by my desk while I'm working and grab it any time I feel the tension in my back building up. I love it.
