Light For Pain
I bought this to try because I have knee pain and arthritis of the hands. It works if you put on at least five to ten minutes an area. I sometimes put it on my knees for 30 minutes, it shuts off on its own at 30 minutes . I use it on my hands and it helps relieve pain. I use it everyday usually at nighttime and l am happy with my purchase . I thought it was a high price for what it is but it helps and I don’t regret buying it !
