My wife and I were introduced to the zero water system 3 years ago and have been totally satisfied with the quality of all items purchased.  My wife uses the glass 40 cup dispener for all her drinking and cooking needs.  She loves the ease of filling this container directly at the sink counter and stores the dispenser unrefridgerated for her drinking and cooking needs.  I use the 11 cup ready pour container that is stored in the refridgerator and use it for making fresh coffee and iced tea.  We both quit using our ice maker and use ice cube trays filled only with zero water.
