I tried this device because of a chronic back problem. Thought it would be a lot better than just a cold pack that I get out of the freezer. I was wrong. Save your money
I placed this order ahead of surgery and then it was canceled. I have been trying to get a refund ticket sent to me, and I just get ignored. Bad Customer Service!
Unbelievable relief for Rotator Cuff post-op! Magical! Highly Recommend this product!
