Amazon has a large selection of the red light devices. Good prices also. I have had.mine for several years. I have had fibromyalgia for 26years with daily pain. I'm scared to use every day but at least twice a week and it seems to help! I also have a compressed disc that I have had several steroid shots for and I use it on my back. I now have osteoarthritis of my knees and will wrap it around my knees! After getting very comfortable with it, I have placed it on my head. I just had a thought, maybe it will help my IBSD, so I will wrap it around my belly.
So far I have not had any burns!!!! But, I have learned that after putting around knees there may be a little pain and then it all feels better!
