Bests & Worsts Reviews from Amazon

This light is totally confusing/amazing, in my mind it shouldn't do what it does, but it does. Reviews from Amazon and many other sites painted it in a positive light and with the 60 day money back guarantee it is definitely worth a trial.I have a knee that has hurt for over 10 years and had arthroscopic surgery 9 years ago. One of the things about growing old, you often wear parts out. I was told my only option at this point was a complete knee replacement but that I might not be able to tolerate the pain due to current medications and allergies. I needed a cane to walk more than 20 feet, so what could I lose and tried it on my knee first. Then used it on a shoulder where I have been unable to raise my arm above my shoulder for the past 3 years. TOTALLY surprised, it worked. When my wife arrived home I asked her if she noticed anything different as I walked into the room. "You're not limping". Watch this, and proceeded to raise my arm above my head, without pain, without assistance. "What did you do?" I told her it was that little light I had ordered from Amazon. So now I have this light that looks like a large EDC flashlight but works like a doctor prescribed it. Is the pain completely gone, no, but maybe 90% for me. I can still feel the pain in these joints but they no longer stop me from doing the things I haven't been able to do for years. It's not warm to the touch or on the skin but after repeated doses without a break, the light end of the device does get warm. It just does not make the area warm like an IR heat lamp would, it just strangely works. So... Will it remove all types of pain, no. Will it remove 100% of the pain, no. Will it work for everyone? Probably not as the reviews clearly indicate. But it does work on many people and you would be foolish not to see if you are one of them. Biggest negative about it - trying to explain it to people who have no idea what you are talking about, they look at you like you're goofy.
