I received my 80Qt Portable cooler and when I turned it on the day after I received it the refrigerator side cooled to 37* in about 20 minutes which was impressive but the freezer side didn't work. Customer Service said they would send me a new one the next day and sent me a prepaid FedEx label to return the 1st cooler. Charles was awesome in helping to expedite the process as I was going camping a week later. Charles went above and beyond my expectitions to make it happen!!! The construction is very strudy and I loved all its features especially the locking of the digital screen...as not to accidentally change the settings or turning it off. The wheels and extended handle makes it Very maneuverable for this 116lb gal. It was also very quiet. I was impressed with the overall construction of this cooler and would highly recommend it. I only gave it 4 stars due to the freezer section not working. I will update after I receive my replacement.
