The ultimate portable cooler!! They gave it as a gift to my father who always wants to have ice with him. He never separates from it, it's durable and keeps the cold exactly as an igloo in its category should. (He has bought a second one and has given two more as gifts to friends, such enthusiasm).

I haven't had it for long and it has seen little use so far, but I was impressed that even without ice inside, it managed to maintain the temperature of a six-pack of beverages for several hours.
The size is quite small and convenient to permanently stay in the car trunk. Useful also when you want to keep takeaway food warm until you get home.
