I have been having problems with my right knee, but using this product has given a measure of relief. The more I use it the better my right knee feels.
It broke less than a month after receiving it, and I spent hours between phone calls and emails attempting to get a resolution, as I wrongly assumed that by registering for the warranty, it would be simple to have it replaced. Boy was I wrong, and its still not resolved. Lifepro seems to believe everyone has the latest technology to provide videos, photos(which would do nothing) scan this and that and so on. Further, first its basic info, then that is not enough, then its something else, and you do that, and then they want something else--its like they want you to give up--what happened to the customer buys something, it breaks( the adjustable portion collapsed into itself and seized) and the company replaces it due to having warranty and being so soon after purchase. Do not rely on registering your warranty to provide you with an easy solution to any issues--very disappointed in Lifepro.
