This device is wonderful and really works very well. When the meds don't work this will relieve the pain for a while after it's use. It also makes for a nice neck pillow (better than those you see most people using as it will support your whole head).
I seldom review items but this simple little product has helped me so much I feel compelled let others know about it. I have suffered from neck and shoulder pain for many years. Doctors have told me this is due to degeneration of disc and joints in my neck. I tried everything and nothing worked until I tried this thing. I use it one or two times a day and it almost completely relieves my pain and stiffness. I can even go up to about a week with out using it before the pain begins to return. This product has really changed my life. I am beyond grateful.
