Now with all the arguing aside for a moment I'd like to clear up what we know as fact. In my research no Heavy metal tests, fat tests and acid tests can be found on any of the distributors sites. Although claims of colour analysis charts are very wide spread. So is there anything in the byproduct that can be tested to prove this device is actually working? These are the facts right now. Thats it. It may work, but it's not pulling heavy metals, fats or acids out of the body, and this unfortunately is what the customer is typically sold on. I'm sorry if some of you are stuck in the reality tunnel that suggests otherwise. Enjoy your placebo foot baths.
