I purchased a 77 quart model and have used it 3 times over the last couple of months and have been completely satisfied. It was able to keep our food cold for several days as well as keep ice from melting. It is a very high quality cooler and very well built. I really like the handles which make it easier to carry since it is a large size cooler. I would highly recommend the LifeTime 77 for anyone looking for a high quality well built cooler at a fraction of the cost of comparable coolers.
