This works very well for us. The capacity is sufficient for most trips that we take. The only downside to this cooler is its weight. However, the wheels make it easy to move around. I would not want to buy a cooler of this capacity that didn't have wheels. One other positive are the latches. They are very easy to operate and have the Yeti latches beat hands down. After owning this cooler for about a year and using it numerous times, I am very satisfied with how long it keeps things cold. It keeps a full cooler cold enough all day with only a couple of mid-size freezer packs. I did use it once with a 20 pound bag of ice and a couple of dozen drinks. It kept things ice cold for at least 3 days as we used up the contents. Again, the latches work great and in my opinion are much better than the rubber latches used on the Yeti coolers. Although it takes both me and my wife to lift the full cooler up into the back of the car, we are able to move it around by ourselves due to the wheels which make pulling it easy.
