I bought this cooler last weekend. I put 20 lbs of ice in it before adding the meats and other frozen/refrigerated items, and another 40 pounds of ice after adding everything. This was done at about 9:30 at night, by 8:00 the next night most of the ice was melted. The high temp during the day was 82 degrees, and the cooler was in the shade under my deck. I expected to not have to continually add ice all weekend, but that's not what I got. Also there are no the downs on the cooler for transportation. The cooler looks good but looks don't keep things cold. I have a 20 year old Igloo that performed better.
