I have used this product for a few days and I am loving it. It straps to my legs comfortably around my knees and the material is very soft. I like how it feels on my skin. The heat and vibration has helped me a great deal with my knee. It reduced my swelling and I have a better mobility as well in just the first week. I am looking forward to the next few weeks to see how this product will continue to help my rehab.
