VERY happy.Just want to make sure you are still happy with your purchase. Also how hard does your Isotherm work to get your icebox to 42 degrees? Could you make it colder if you turned up the setting? I looked at the defender catalog and there is a model without the intelligent power management for less money but I am sold on the smarter model. All experience and wisdom greatly appreciated.
The duty cycle is very low. Really hard to tell, because when on AC shore power the box goes down into the low 30s, and slowly warms to 40 on DC power over a day. You can make it colder as a setting, but then you turn off the smart controller feature. My unit on freezer mode will freeze my box down to 6 degrees.
