The representative I talked to before purchase and ordering was great. He answered my questions and made the purchase easy. The shipping was fast. The hook up for this filtering system was not extraordinarily difficult for me and probably would not be for the average DIY homeowner with common sense. I could tell the difference in my water quality almost instantly and I have only had it in for a couple of days so far. No more chlorine smell and dry skin caused by the disgusting chemicals added into the water supply by the city. I can now feel good about exposing myself to the water in my home. Well worth the money!
