I am a very skeptical person. After 15 years of fighting my knee, and a month ago finally having a partial replacement, not only does my knee kill me, but also my back bc of how I have to walk. While at a festival, we saw this husband and wife with their booth for this...I am swearing by this and have also gotten my man to love it with his shoulder, and my mom to love it with her knees and hips. I can't wait to make another order and help more people learn and love this product and help them in their everyday lives!!!
