Recently bought this cooler for tailgating season, but had the opportunity to put it to the test early. I went on a fishing trip to the Louisianna coast. After arriving (Sunday) I stopped at one of the bulk ice vending locations and filled the cooler to the top with 60# of ice. It stayed in the back of the truck the entire time and the truck has a locking taunou cover. Of course setting in 95+ temps under a black cover probably wasn't the best thing but I went with it. When I'd open the bed of the truck, it was obviously hotter than the ambient temperature. We Fished the next day and that evening I went to put our cleaned and bagged catch of the day in the cooler. I opened the drain to see how much melt there was. I'd estimate about a gal of water came out. It seemed like a lot, but inside it was hardly noticeable. I was afraid I might not have room for the fish. I managed to move the ice around and pack the fish in there. Fished the next day (Tuesday) and caught more Reds. That afternoon, when I went to put our catch in I literally had to scoop out ice into a bucket to make room for our catch. I then poured the ice back over the fish and it was still packed the top. I didn't drain it any more, just left it as is. We drove 8 hrs to my buddy's ranch in east Texas that evening. Wednesday was another hot sunny day. Got home that evening and divided up the catch. I drained off the melted ice. I'd estimate maybe another gal. I put my fish away and left the ice in the cooler on my back porch to see just how long it would stay. It faces SW and really gets heated up after midday. Thursday, Friday an Sat were both hot sunny. Sunday morning, today 8-5-2018 I go out and there is still probably a 5# chunk of solid ice. I went ahead and drained off the water, dumped the ice and washed out the cooler. I'd give this cooler 10 stars if I could. Love the latches, they are easy to open, yet holds the lid tightly closed and very sturdy. Strong hinges and it so nice to have a cooler that the lid will stay open when you leave it open. My go to cooler was a big igloo with the plastic hinges. The lid will not stay open on its own, it always want to fall back closed so on those coolers if I wanted it to air dry I'd have to prop it open. Not on this beautiful Pelican cooler, the lid stays open. I'm so glad I went ahead and got this one with the wheels. I was looking at the 70qt but the 80qt had the wheels. It was quite a bit more money for the wheels but well worth it. I can't imagine trying to lug around a 70 qt with no wheels. It would be a 2 man operation. The fold down handle is awesome. Out of the way when you don't need it, and is the perfect length and angle to make moving this beast around where you need it an easy task. Definitely give this a must buy if you are looking for a High Performance cooler. I may have to buy the 55qt too with the wheels on the back for when I don't need one quite so big. Then all these igloo, and coleman coolers are going in the garage sale or the trash.
