I had a very unsatisfying 'go-round' with these people about 10 years ago, before the slick website, and when they were sending out promotional VCR tapes made in someone's basement or garage with a home recorder.
The pix of the product were long shots (its a small device about twice the size of a cell phone) and you never could what the controls were, or tell what it was - that you got for your $600-$800 (but $200 off if you bought it within the next 48 hrs!!), except a plastic foot bath and some sort of 'control'. they were hot on selling the (overpriced & ridiculous shipping $) additives for the foot bath (I think epsom salts work... or is it baking soda?) and other salves or cremes.
I came to the conclusion that they were 'snake-oil' salesman, but have since found out that they do honor the money-back warranty.... if you meet the requirements.
