We bought this cooler based on label stating 7 day ice retention. We have used this cooler twice now, first time beach trip put drinks in cooler along with 40lbs ice, after 2nd day we had to add 10lbs ice, by day 4, ice is completely melted. Second time using cooler, we go camping on monday afternoon. Packed cooler with frozen foods, stopped for drinks and added 40lbs ice. Today is friday, I checked cooler this morning, all ice is melted, drinks are bout room temp. Should have saved some money and bought an igloo, about the same results. Very disappointed
