We have a 55 quart cooler that we use for camping and it is wonderful!!! The last trip we noticed the ice was melting faster than normal. We chalked the issue up to a warped seal. We were not ready to give up on our cooler because we love it so much. I contacted customer service via email to try for a resolution. I expected a response in a couple days but they responded within a few hours. By the next day we had a resolution. Well done Lifetime! You have a customer for life!
