I can feel the warmth, however mostly it has given me more mobility. I am on my feet, on concrete 6+ hrs a day and my knee becomes very stiff when at rest. This has helped relieved that and helped with pain!
I like it and it helps my knee, but I bought two. One for me and one for my wife. I had to return the one for my wife because I wouldn’t fit her knee. Your products are not made for a larger person and that is to bad because that is a market you are losing. Look at stats about the weight of America and you will see a new market to reach.
I bought for my wife’s knee pain She had replacement knee approximately 19 months ago and still has pain She used for a month daily 20 minutes a day No results
I purchased this for my husband because of a recent knee injury. He uses it every morning and evening. He is able to sleep through the night without leg cramps. This is the best thing that I have purchased in many years.
