"Initially, I was a little hesitant to purchase the Shoulder T Shellz. I begin using it on a regular basis in between my sessions for my shoulder. When I exercise I use cold compress for 20 minutes. During other times when relaxing I use the T Shellz wrap. It works for me and it is the right thing for my shoulder. I believe in the cold-Hot treatment for healing muscles and ligaments. Thanks for a great product. I have recommended it to several other friends."
