Looked at several different coolers, but didn't want to spend a lot of money. After doing some research, I decided to purchase the 55qt lifetime. The cooler worked great for about a year, held ice longer than any other cooler I have owned, but then noticed that my ice retention was decreasing and the seal area was bowing in. I contacted lifetime and made a warranty claim.  The customer service rep apologized for the inconvenience, and ordered a replacement cooler.  It was out of stock, but shipped less than 5 days later. All of this at no cost to me! The replacement has an improved seal area and should be better that the original.  I would definitely buy a Lifetime cooler again
