For me personally these bracelets do work. I have used one for about 18 months. I had suffered a lot of pain and discomfort in my neck and shoulder, after a fall in 2001. After spending lots of money on various treatments, none of which worked, I resigned myself to the fact that this was something I had to put up with. Then I saw an article on the TrionZ Bracelet with nothing to lose I purchased one, and never looked back. After a few weeks I realised I was not in as much discomfort as I was and I now have no pain whatsoever. I have purchased this one for my partner, who suffers on occasion with pain in his achilles and lower back, although doesn't like to admit it. , He plays golf and runs and is now taking up windsurfing he has always been somewhat sceptical about my bracelet, so imagine my surprise when it appeared on his Christmas list. He has obviously been impressed with my recovery and is going to give one a try. I wear mine constantly and only remove it to shower or bath and to wash it in warm soapy water once a week to freshen it up. If you are suffering and want some non-medicinal pain relief, you have nothing to lose - try it, you will I am sure, be pleasantly surprised.
