I bought one of the Zero pitchers originally, but changed to the larger volume dispenser this past summer and am very happy with the convenience it provides me for clean, good tasting water for cooking and especially for my coffee and general drinking.  The gauge provided keeps me aware every day of the purest water that I am drinking.  And best of all, I'm glad I searched the internet about two years ago for a comparison of the water purifier products on the market and learned that Zero is the best.
