This is a very fine cooler. However, the only way ice will last for 4 days in this thing is if you bury it in a snowbank. When I got this cooler and used it, we stocked up on ice for the approaching hurricane (we live in Florida, the name of the hurricane is irrelevant). After two days, I noticed the cooler had leaked bigtime. Upon inspection, I noticed there was no bushing on the drain plug. So I removed the drain plug assembly, installed a [tight-fitting] rubber o-ring, re-installed the assembly, and it now works great. No leaks! The cooler is a  bit overpriced considering the assembly was obviously incomplete.
