This item is the best investment I have made for relieving pain. My Home Therapy Specialistm used her's on me and I knew I needed to purchase one for use with my wife and myself. I love using it on all of the sore spots on my body. My wife loves itI think more than me if that is possible. She has had pain in her left shoulder and left hip for months and after using it she said her pain was gone. Thanks for making a product that individuals can use.
