NICE!
I absolutely love mine. Sure, some of the programming can get a little frustrating but that goes with ANY controller and overall GHL is one of the easiest to program. Especially the basic stuff. It even has auto water change programming built in so no need to buy a Genesis or other third party AWC system. These things are built like tanks, too. Absolutely kills any of the other popular controllers.
So which kit did you get?
I have the 3ex main unit, 3 probes (cond, ph, temp), one optical and one mechanical level sensors, the vortech control module, 2 PAB PowerBars, the 3-pump doser, and the Touch Remote Display (check out my build thread for my recent Touch custom install). I have a redox probe on order. And eventually I want to get one or two of the flow sensors as well as at least one leak detector.
