I read the pros and cons but I still wanted to try it for myself. Although the water did come out pretty dark and ugly, this is not consiered to be determining proof, as even if you do nothing but fill the small tub and put in the electrodes, the water will still come out dark. Perhaps it does something and perhaps it doesn't, but what finally caused me to stop was the cost. $40 bucks a session a couple of times a week is too much for me, so ultimately I prefer the magnetic clays for foot baths. These are not cheap, but they are more cost effective in the long run and should produce as good a detox function as the foot baths.
There is a commercial link to LL's magnetic clays somewhere at the bottom of CZ's main page, but I have bveen purchasing them since way before they were featured here as a CZ donor.
I also like the Bodypure foot pads. Look for the old Dr.Vinograd forum. He was selling products, yes, but he is as decent an individual as you can find anywhere. The old forum is full of this kind of information.
