Bought this cooler and it was delivered on June 31st, 2019. Loaded it with ice that night, (two 25 lb bags). Saturday broke open the bags, loaded with frozen food and cold pop. Headed for upper Michigan. Seven hours later, no water melt and full of ice. Ice lasted for seven days. Two more bags for trip home and ice stayed for seven hrs plus one day. Back of gasket came loose when opening cooler, put back in place, and it worked great. It was a great buy for the money and I am very happy
