The immense advantage, slight fever measure with whining children and babies was indeed mentioned several times. Just when you repeatedly have to measure and to every time would undress the child, the thermometer is very helpful. For criticism of "inaccuracy": With a little practice you know how you have to fix it at the ear, so there are good results. In the operating instructions are also to advice. I measured it suspicious rectal beginning. There, the temperature was 0.3 degrees higher, respectively (this is also the general criticism of the measure at the end, under the armpit, the tongue, under the arm or in the ear, that you do not get the exact body temperature). But if I can measure several times with the Ohrthermoter in my feverish child in the night, without waking him and just 0.3 degrees to count - then I know if the fever rises or falls, and whether it moves in a critical area or not. A star deduction for the plastic waste by one-off caps.
