Some people believe they work and other people say they don't. I swear by mine and only take it off to shower. After have back pain for years following back surgery, since wearing mine, I no longer hurt at all. It's supposed to be something about the magnets in the bracelets. Whether it is the bracelet working or it's all in my head, all I know is that I feel great again ~ finally!!!
I want to offer my two cents on this. I purchased a bracelet a few months ago, as it literally did nothing for me. I've heard, however, that the product has worked for others. Whether or not it can be attributed to the placebo effect, I don't know.
I'm not sure, about the the whole placebo effect. All I know is that I had back suregery a few years ago and it hurts like heck when it's going to rain, Since wearing the bracelet it doesn't hurt anymore. I can't say if it works, because I believe it works or if fact it does work. There will always be a debate about it.
