This is a very good thermometer, much more accurate than my previous one, a La Crosse. One thing I find irritating with it though, is the ice warning. I don't need this warning, I live where it is cold and it stays on for 4 months. I am concerned that it uses up the batteries, and it is irritating to look at. I can turn it off temporarily, but it just comes back on.
