This is a very easy to use thermometer. It is not complicated with a lot of options. There is the power button on top and a button on the back to change between Fahrenheit and Celsius. I like that the top of the thermometer can be moved around. That came in handy while checking a roast, and I did not have to remove it from the oven but could still see the read out of the temperature. Be cautious if you have a husband like mine that wants to do a quick clean up after dinner and just slides it back in the case before washing the metal part. I was a little concerned because it looked like food might have gotten inside the case but when rinsed with water it appeared to be clean.
