I’ve had three Bioflow wristbands now and swear by them. When I lost my first one I went a couple of months without and suffered a steady decline in mobility whilst not realising why until I purchased a replacement when upon putting my new replacement wristband I felt almost a surge of energy go through my body and my mobility slowly returned. I’m a semi retired landscape contractor and have abused my body over many years, although the Bioflow will never repair all my damage it goes a long way towards it. I now have a basic band for work and a nice leather strapped one for every day which stops my shirt sleeve from getting mucky from the work one!
