Just moved into a new home. Got a call from these people at Pristine offering us 2 $50 gift cards for gas, if we would schedule an appointment for them to come test our water and tell us about their products. The guy came and talked for about 2 hours. We were not sold on signing any contracts for thousands of dollars, that night. Before the guy left, we asked him about the gift cards that we were promised. He said he would have to go let a lady back at the office know and she would have to mail them to us. We never received any gas cards. There are a lot of similarities between my story and what I've read on the previous review. It seems that these people are fraud. I'm glad that I dodged that bullet.
