I bought this thermometer for use with my daughter of 18 months from the time period of high fever, however, it categorically refused the traditional thermometer, and use of the thermometer with plug in the ear turned out to be a failure because each shot gave me a different result. I found the ideal thermometer Braun, easy to use, an on button and an easy to read screen. The screen color that varies with temperature ... Power take the temperature of her child her no contact is really a relief and the balance of power is avoided with the child. I do not regret my purchase.
