Pros: I use it on my Knees, Fingers and wrists. It provides me with pain and stiffness relief ( or at least I believe it does ). I feel relief almost instantly. I use it in approx. 5 min sessions. I don't know it is has any medical benefits but I sure has me convince it works for me. PS. I also use it on any wound's I do not run it over the wound I run it from around the wound up to the wound, as the result the would appears to heal faster.
