I have done a lot of research on alkaline water and alkaline water systems and from what I read, Kangen is one of the worst. www.ionizersreviewed.com seems to be a neutral source, and they found that Kangen is WAY overpriced. They don't use the newest technology and they have an additive they use to add to the water to make it more alkaline.
There are other models that are much cheaper that will give you better results.
I drink alkaline water but I couldn't afford a machine so I made my own. Not everyone is up to that task! That being said, my machine cost me $50 and it makes 2 gallons of alkaline water and 2 gallons of acidic water at a time. My family loves the alkaline water and I did detox for a week when I started it. Now my daughter won't drink anything else and my cat who was fat lost weight and both of their hair is silky smooth.
I highly recommend the water! It tastes great, is super hydrating and we love it.
