Product review (4 stars): So far so good..
So far so good....it is very quiet and seems to be sturdy made. I keep a freezer thermometer in it to make sure the temp stays where i need it for food storage. In the trunk of my car it ranged between 40 and about 47. In a house or a hotel room it stays between 33 and 40. I have not used the heat setting and likely never will. I use the cooler for week long stays in hotels and travelling for work it has so far met ir exceeded my expectations. I have noticed that metal cans seem to get way colder than plastic bottles but my food has stayed the same temp as they would in a fridge.
