I consider myself to be a fairly intelligent person, but I absolutely cannot seem to get this thermometer to scan consistently! I have read and reread the directions, but it only scans one out of ten times. Like other reviewers have said, it will give me such a ridiculous range of temperatures that I can't even guess as to what might be right! I bought this because of the reviews...i mean 3,000+ reviews and almost a 5 star rating! I was expecting it to be golden! What a dud!
