I got a 55quart Lifetime cooler as an early Christmas present in 2019. The cooler began to warp and didn’t seal properly. (This cooler was one of the older designs). I requested a warranty replacement and was given a replacement order confirmation within a day. 
Great customer service. I am in the Self Serve Ice Vending business and carry a lifetime cooler in my truck all day everyday. This cooler holds ice better than my 70 quart Yeti and MUCH cheaper. Good hinges and the drain is better than any other cooler I’ve ever had.
