I love the visual readout of this, really a super design. Too bad that the main function of this thermometer(taking temperatures) was NOT well designed. It always reads very low, but not always the same. It would be one thing if you knew that you always needed to add 2 degrees to be accurate, but sometimes 2 sometimes 3. Not what you want to be worrying about when you have a sick child. Too bad. Buy something else.
