I bought this cooler 2 days ago. Filled with frozen food and ice to the brim, as per directions. Sat in a garage for a day at 60 degrees. In a van traveling for 7 hours in the back. Ice melted, food thawed, water with thawed food leaked out of cooler into luggage next to it, and into the stowed seats below it. Extremely poor quality gasket, extremely poor quality fitting of lid to cooler. If it fit properly, maybe it would be better seal. Customer service has been emailed. Definitely should have read other reviews on this cooler before purchasing.
