I have had this item for over a year.  It is wonderful.  The water here is terrible and some days it smells terrible and tastes worse. Since I have had this Zero filter, the water always tastes great and I am so much more comfortable drinking it and cooking with it.  The dispenser is very easy to maintain and my filters last from 2-3 months.  This is a quality made product that actually does what it says.  I love it and am so thankful to have discovered it.
