The duo camera is very impressive, easy to use, great pictures. The guide camera just works. Certainly simplifies the setup. My disappointment is with the inbuilt ASIAIR. Coming from a stand alone ASIAIR Pro I expected it would be the same, it isn’t.
There is no control over the DC input/outputs unlike the stand alone unit. This impacts the ability to control the power level going to, say, the dew heater. If that isn’t an issue for you than this is a great all in one unit
