After reading a lot of reviews - good and bad - for this cooler, I ordered one. This one replaces a much smaller 9 can cooler (different brand). First of all, it is very quiet. Above road noise, the radio, and the cabin fan, I can't hear it at all. Koolatron may have gotten some bad fans - a lot of people complain about noise - this one is infinitely quieter than the smaller cooler. This cooler would benefit from a gasket for the lid (which I'll probably add). The only thing that is slightly off is the interior fan shroud - it does not fit well, and I'm not sure if I can straighten it or not. There is a bit of a gap all down the right side - which means that some of the air is not moving across the cold plate. I think our friends to the north could do a bit better. Other than that, this cooler is great. Plenty of room, and cooled down to 40 degrees in about 40 minutes - in the car. I'm going to try an inverter and 120 volt adapter to see if that's any better or different than the 12 volt plug in. Unlike the much smaller coolers, this one has an interior fan to distribute the cold air - which means you can't totally pack it full - the air needs to circulate. Overall I'm very happy with this purchase.
