Just got off the phone with the customer service here, and boy were they terrrible. The Kent Deion 200r that was recently purchased through them is already exhausted after less than 70 gallons of water being made. When purchased I was told 20,000 gallons or 6 months. I called to find out about returning the unit, and they laughed. They said that they couldn't take it back and that I would have to talk to Kent marine for warrenty info. I told the guy that I would post reviews about their customer service, and was met with a threat of a law suit. I would not order again from these guys even if they were giving away everything they had. TWO BIG THUMBS DOWN!
