If you read the instructions and then it so applies as stated it is working properly, the beeping really bother in his sleep now not if you use it correctly it will beep so only briefly. Displays very closely, have been measured in the Po! As I said: Really watch how it works, then simple, practical and fast, better than an ear thermometer, because that interferes with my son in his sleep! It really is only ne fever verification when very high fevers should anyway remeasure in infants and babies in the butt!
