Bought this cooler for a car trip to keep food items cold till we got to the hotel. Filled it with food and ice, made the trip(less than 24 hrs). When we arrived all the ice was gone  just left with cold water. 
The reason I bought this cooler instead of another brand and paid more money for it, was on the claim it would hold ice for up to 5 days! It did t even make it one day and it was not a real hot day! 
Other than that it seems to be a nice cooler, haven’t had it long enough to rate the durability.
