Matt was very patient with us when we reached out to him. It was a straight up transaction and no BS! Matt delivered and was very responsive- amazing sales person and no pressure. Tech guy that installed was amazing as well, he took his time and was very thorough in explaining everything. The system is great and no more hard water!!! We also did the reverse osmosis - best purchase as we don't have a ton of water bottles anymore! Thanks Crystal Clear - highly recommend.
