“Easy to install. Water tastes good, but maybe not as good as my old RO system with an alkaline remineralization filter. I like having the UV purifier at the end as peace of mind and RO systems can get bacteria problems over years of use (as with my last system). I'm reducing the rating by one star because warranty registration fails every time with "No Corresponding Order No.".”
