I have had my Zerowater dispenser now for about 6 months. I used to buy alkaline water but love this filtered water so much more. I also love the idea that I can test the cleanliness of my water with the included tester. The water tastes great and I know my family and I (including our dog) are drinking safe, clean, delicious water. Just be prepared, the filtering definitely takes longer than other well known filtration systems on the market.
