I was hesitant to spend money on a water filter,but now I'm so glad I did. I also did some research and decided that this system was the best I could find for the price. The reviews helped me make up my mind. It was easy to set up(even for un-handy me!) and now I actually like drinking water. I needed to kick my diet soda habit,but didn't want to drink water out of plastic bottles. This water tastes so much better than bottled,and more importantly is a very necessary ingredient in health maintenance.
