I like mine so far...haven't played around with it much. If I have one complaint it is that they changed quite a bit of the programming interface between this and the AC3. I was pretty good with the AC3 and haven't had time to learn the nuances between the two.

I would also like a graph or chart telling me the state of a timer through out the day so I can retroactively see what the controller is doing. This is possible via website as I had it working for a while on my AC3. Just seems like something they should have built in to it by now.

I really like the iphone app and the neptune controllers. It is like having a remote control for the tank. I can turn equipment on or off to do a water change or other maintenance without even pushing any buttons or touching cords.

To use the text alert, do you just set up an email to text based on the cellular service.... is phone_number@txt.att.net would be at&t's? or is there another way to do that?
