“I bought these patches for the first time recently as I wanted to try a natural way to alleviate some knee pain and in my case they definitely made a difference. I can do without them most of the time but I'm happy to have them on standby for when needed. In my case it needs to be on for a few hours to work and the most relief is when I leave one on overnight when it obviously gets the best chance to work. Based on my experience I would definitely buy them again.”
