I have had my Zero Glass Water Dispenser since pre-orders were taken and I received it.  I absolutely love it!!  I drink tons of water and sometime refill the dispenser 3-4 times a day (use for drinking, making coffee, tea, etc)  The filters last a really long time ( approx. 2 months) considering I run so much water through it.   I also have the stainless steel pitcher that I keep by my bed.  I highly recommend Zero Water
