As a child I felt the measurement with the thermometer at the bottom rear cover always shed a very, very uncomfortable and have a lot of tears. Many infants it is so, so I think that will shudder as a thermometer like Braun little less patient. What you have to bear in mind, the surface temperature is imho inaccurate, as if their core temperature (measured at the lower rear cover, mouth) Measure, which is normally not affected by the ambient temperature. Personally, I'll let the device to measure the temperature always under the armpits. The armpits are imho closer to the core temperature tuned, even if it, despite everything still runs on surface measurement, I think here I have the exact results.
Summary: The forehead thermometer does exactly what it was designed and is very fast. As written, the measurement on the forehead is rather a trend measurement. But a forehead thermometer one can also be measured under the armpits. ;-)
