The cooler does what it says. I was also surprised of how quiet it is. We keep it our kitchen next to our sliding glass door and I wanted to see if the temperature would change near the door. All day it keeps cool at 56 degrees. I gave it 4 stars only because the buttons are sensitive. I'm pretty good about opened the door from the side, but my boyfriend opens the door from the top and accidentally presses the buttons. It's an easy mistake to do. Other than that it's perfect.
