Product review (5 stars): As advertised! (Rare in my experience...)
Stood up to a 10-day car trip where it ran almost continuously.  Kept my food/drinks cold, and was well enough insulated that I could use ice in the bottom to keep things cool when the car wasn't running.  At night I would just bring it into the hotel room and plug it into the wall.  Sturdy handles and wheels, and reasonably quiet. I only wish it had a drain hole to make it easier to empty ice melt water.
