I bought this cooler a week ago. I bought a case of water and 10 lb bag of ice. Put about a 1/3 of water bottles and put in ice. The water got chilled pretty quick and stayed cold but ice was gone by the next day. I did keep cooler inside truck. I was working and had no way to secure it in truck. The next day i put the rest of the water and 20 lbs of ice. Again it was kept in truck cab. Both days were in the high 90’s temperature. Again water got cold but all ice gone by next day. Did not drain it when i refilled it. Over all cooler is ok. Not sure im going to keep it
