A cheap & easy way to impress your local Health Department! Seriously, I purchased one of these thermometers for each refrigeration unit and they agree within 2 deg Fahrenheit of built-in and infrared thermometers. They are also very easy to read. As others have mentioned, the suction cups aren't that great. Even when they're sticking the thermometer sags and I have to look up at it to read it. I move them around periodically so it doesn't matter. An excellent value overall.
