First year I gave it a solid five star. It would keep ice easy for three to five days in the back of a closed up suv in the summer heat. First time out year two all the ice melted in a day and a half at seventy five degrees! I found the whole front by the latches was warped inward and the seal didn’t even come close to the lid. I guess you’re not supposed to store it for any amount of time with the lid latched? I guess I have a 77 quart storage box now.
