We had our system installed a few months ago. Right away, we loved it! There’s a noticeable difference in the taste of our morning coffee. I don’t have to clean the shower doors as often, and the sinks and fixtures stay spot free and are much easier to clean. The sales rep (Anita) was very knowledgeable and well-informed about the products. She answered all our questions but put no pressure on us to purchase it, but we sure are glad we did!
