After one week of use, the cooler no longer keeps ice for a day, let alone for 7.  We purchased the cooler in July used it for a week while traveling, and I was very impressed with the cooler keeping ice almost 5 days considering the temps were in the nineties. A week ago we had company an loaded the cooler with ice and drinks - equally proportioned as recommended and the ice barely made it through the day - what's worse is we had it in a cool garage.  I am now less than impressed and would not recommend this cooler.
