Some write that in repeated measurements come out different results, but this is even described in the manual. Braun recommends that measurement always in the same ear and each time with new protective cap so that the results are not distorted.
In the manual, a table is also indicated the extent to which the measurement results in the ear may differ to the rectal or oral measurement results and that this völligst is normal.
Schön is the on and off switch to the thermometer immediately after use to back off, so no need to only wait 60 seconds until it automatically turns off (such as with other thermometers).
Overall, this thermometer is highly recommended in any case!
