GHL may not be the way to go but I can't imagine the programming is that hard but never having used one personally I can't say. In all truth I'd really like to see a controller from Ecotech as I'd be willing to bet it would be the best controller offering. As far as customer service I manage over 20 apex units, most of them gold edition plus who knows how many extra modules yet I still have to call and leave a message for them to get back in touch with me at their convenience. I don't see what about that is above and beyond lol. That seems more like what I'd expect to get as far as customer service from jebao not an American company charging a premium for their product. You don't get this from any company that I'm aware of but Neptune, certainly not Tunze, Cobalt, Ecotech, Marineland or Hydor which fortunately are the only other products I've ever needed service on in the last 20 years other than Neptune.
