This company has some of the best customer service I have seen in a long time. Professional and reliable. Called me every step of the way. Even reminder calls about the upcoming appointments and verification on what I am getting. I am very please with the product. I want to say that I have a sensitive palette since I cant drink tap water without vomiting. Drank a nice full glass after they installed it and ran the system for a bit. It was great to finally be able to drink good clean water.
