Recently bought and returned this cooler. Before I even attempted to see how long it could hold ice, I wanted to see if the lid was water tight. Filled up the cooler with water, closed the lid shut, lifted the cooler and water was spilling everywhere. This cooler might work for you if you don’t plan on moving it. However, how long can it truly hold ice if the lid isn’t even air tight? Should have looked at YouTube reviews before purchasing since other people have reported this problem as well. Would give this cooler another attempt if the lid is redesigned
