My four star rating is for the great service I’ve received so far from Lifetime. I sent photos and they are processing and sending me a new cooler. So I will have to rate my first experience with this cooler as a 1 star so far. After one use the lid was warped. We continued using and the ice melts by the end of the day, much more quickly than the label claims. We camp a lot so buying a ton of ice was a hindrance thus why we bought this cooler. Once we get the replacement, we will do a new review if it is better quality. I’m nervous it will warp as well. Stay tuned
