Well I have to admit I agree with your line of thinking. It is pretty unbelievable that he has been in business for 30 years though. As I posited to QE a while ago, I wonder if the removal of fluoride by his machine has something to do with all the (posted) claims that people feel better after drinking the Ellis water. I know that after we started drinking non-fluoridated water in my house we seemed to have much fewer incidences of headaches, fatigue, irritability, etc. Not to mention that the water just tasted a lot better after being filtered through the reverse osmosis filter.
With a handle like Waterdoc, I am assuming you are in the biz. What is your connection to these products and what products are you referring to that 'work'?
As far as being stuck with no guarantee, my dad probably wouldn't even attempt to fix this machine if it broke after telling him of my experiences with Mr. Ellis.
