Bests & Worsts Reviews from Amazon

I purchased this cooler just prior to going to visit my daughter in Houston Texas. I planned to drive from my home in New York state to Houston. Google Maps says that is about 1,750 miles each way. My car odometer agrees. I wanted something to keep some snacks and drinks cool along the way and did not want to worry about where I could get ice. Amazon, bless them, got it to me the Friday before I planed to leave on Monday. Since it is not a refrigeration unit I assumed it would take some time to get cold. I plugged it in Saturday morning (I also bought the power brick) and let it rum. Since I was not sure if it would really get cold I placed a thermometer inside so I could check. The temperature in the living room was about 74 degrees. By Sunday evening the cooler registered at 30 degrees. I packed the cooler with soda cans and water bottles chilled in the refrigerator. Also, some cut up veggies etc.. Other than the time the unit was unplugged during transport between the car and the hotel room it was running 24/7 for 7 days counting the two before I left. The unit gave no problems while running in the car and the power brick never got more than warm to the touch. Never hot. I used the cooler exactly the same way on the return trip. The only problem I ever had was that some of my cut up veggies froze in their plastic container box. They actually had visible frost on them and were stuck together. All-in-all, I found the unit very convenient to use. It will be in the back seat of the car on any future trips around the country. EDIT: One thing I should add. During my stay in Houston the unit ran 24/7 for 9 days using the power adapter.
