I had a tear in the supraspinatus tendon on my left shoulder and I did active movements. I also took time off from sports and daily activities, but I wasn't seeing a lot of progression. I did some deep research on the internet and I ran into this product. At the beginning I wasn't seeing a lot of results, but I'm glad I did buy this Shoulder T Shellz Wrap. It definitely helped me to get through the injury! It wasn't easy but I did it. Luis from Wisconsin
