Recently I hurt my shoulder and my neck. I told my doctor about the AquaBells and he said "Wonderful. Use them as part of your physical therapy." Not only are they fun to use, they are helping me with the neck pain.
I had seen someone else with the triangular ActiveBells and assumed that I would get the same thing. I like them but hers were by the same company but had more resistance. I only saw one choice on your website. So ... I like them but would have liked the little bigger ones even more.
