Ok got my system in today and i must say AWESOME. I love the press. gauge as well as the dual mode TDS montior gives you the readings going in and out of the system. I had it mounted, and up and running in 20 min. Thats from taking out of the box to watching the TDS Drop as the system ran. awesome awesome awsome. I suggest if anybody has the 200 bucks to spend to get this system.
