Query: Does not operate properly

We bought this thermometer because we wanted a quick read thermometer. When it works, it is very quick. But it consistently gives error messages and it does not function properly. 9 out of 10 times I can't get it to operate and take a temperature. The display for the multiple settings is very tiny and easy to accidently disrupt. Don't buy this and waste your money.
