My wife wanted one I was dead set against it. Thought they were gimmicks, they would not work as stated, would not work in the heat. Well she bought one and boy was I wrong. We used it in SC this summer, upper 90's 100 one day. Kept it outside, dumped the tray in our cooler when it got full, never bought ice for two weeks. The cooler was kept outside in the shade so it made a lot of ice. The model she bought makes 50# a day off f you keep dumping it when the tray is full. The only noise it made was the sound of ice dumping in the tray.
