Product review (5 stars): Keeps its cool in the heat!
Took this cooler to a county fair (90 degree heat and in sunny car).  Ran the cooler before I left, during the car ride there, and during the car ride back. Threw in large frozen reusable ice packs too. Stored fudge in it and when I got home, the cooler was cold and the fudge was not melted. Great purchase. Will be taking it to all the county fairs from now on.  Love that it can plug into both car outlet and regular outlet. Only thing is, you have to run it before you want to use it as it takes a little while to get cool.  Have not tried warming feature, but I really like that feature too.  Not too heavy either and spacious for its size.
