I have this machine, there is no other machine out there that does what it does. I researched for over a year before I bought it. It does make great water when used correctly, but be warned, it is not an out of the box, set it and forget it type machine. If you want more info, I would be happy to share my experiences, and I know of another guy I talked to on Curezone before purchasing who has owned the machine for like 15 years.
