Well since no has replied and I was lurking about...
I bought the "water wizard" in the 90's. Had the UV bulb etc. The water if drunk over time and significantly (at least a quart daily) will seriously clean you out, probably as good or better than fasting. So take it slow. I used to get light headed and dizzy sometimes from it.
In my heyday with the machine I was probably drinking about 2-4 qts daily. Unfortunately, the unit became so clogged I had to send it in for repairs. It was never the same again and I stopped using it.
I'm still debating whether to make the leap again, but for now I'm going to get the water pre-made as a trial and go from there.
Anyway I wouldn't expect overnight miracles. Everyone has different levels of toxins to clean out. The idea is to make you a more efficient machine so everything you ingest works better as well as all elimination channels. I'd give it at least 6 months before I would pass judgement.
Some people think it's a very expensive distiller, you have to figure that out for yourself.
My only concern with the machine is maintenance. Can it just be cleaned periodically and run forever or is it going to crap out in a year from heavy usage like what happened to me with the $500 model in the 90's.
