I cannot say enough good things about this machine but like all alternative treatments, each person must make their own assessments.
As far as what the Ellis machine does, it works on a fairly simple principle. It takes a few ounces of water at a time and boils it rapidly while at the same time exposing it to a high level ozone light that allegedly energizes the water while killing any foreign bodies. It constantly circulates the hot water back into a pan that is always replenished by a cool tap water source causing the rapid cooling before it re-enters the ozone / distillation chamber where some of the water that is vaporized to steam causes a pressure differential which then ejects a few drops of (distilled) water out to the receptacle container.
This process allegedly makes it some sort of 'super water' that surpasses all the other water machines out there. Yeah right!
Anyway, that is what it does physically. As far as what it does to the person that drinks it, the jury is still out on that one but as I indicated by my preliminary ph and alkaline tests it would seem that it would contribute more to a disease friendly environment that detract from it.
Since I am not an expert I can't actually say what physiological benefits one might reap from it though.
