I researched all the mineral water systems before purchasing this one at a great price compared to others. The water flow is great in this system. I am spoiled drinking this great tasting water and get the benefit of the minerals. I also use it for cooking and I even take it with when I go out to eat. The city water tastes so bad after drinking this I can't drink it anymore. Am hoping the minerals will help my osteoporosis too. Thanks so much.
