I have a Q-Ray and I have a theory why people think it works.

if you buy the bracelet for arthritis type pain, you usually have some body movement that you test your pain threshold. Like flexing your fingers, rotating your spine, etc.

Before trying something like Q-Ray, you only notice the pain suffered that makes you think about the problem. However, with the product in place, you are reminded to test when the pain is not there or diminished. So it might create the illusion that the product is fixing the problem, when really you would get a similar result if you would simply remember to check for pain when you don't feel it.

Does that make sense?

On the other hand, maybe the damn thing works. - RJ
