I've worn one for about 2 yrs now. I believe it is more psychological than
therapeutic for me. If I wear it my back does not hurt. My back will also
not hurt if I am not wearing it and have not noticed I'm not wearing it. As
soon as I notice I forgot to wear it, my back starts to hurt.

I do like how it looks, that is why I keep wearing it. I tell everyone who asks me about them the same thing, "It's all in your mind. If you feel less pain when you wear it, it is probably because you want to feel less pain, not because the bracelet works medically."
