I am so impressed with Bio-Flow. I have been wearing one of the bangles for about two months after being given it nearly 16 years ago and thinking it just a fad sort of a thing. It has made such a huge difference to my Arthritis. I am able to walk again with my Dogs and unless you are a walker, you will never really understand what that means to me. I have bought two Collars for two of the four Dogs, they are making a massive difference to both of them, I have bought my Husband a Leather wrist band one, for his back pain and it is helping him, and now I have just bought my own two toned Bracelet which I will wear 24/7 because I know and trust Bio-flow, I will never be without one. I highly recommend wearing one of these bracelets. Do not be tempted by one of the many, many knock offs out there that claim to do the same or better, Trust me, they do not. I have bought one and was very disappointed with it. It looked lovely and I still have it and will wear it, but only as Jewellery not as anything that will help me. Thank you Bio-Flow, for giving me back my independence. Dawn McKenna
