This thermometer from Braun works very well! I unfortunately can not buy on Amazon, because we penetrate for our two year old daughter of a need. Since only the pharmacy where it was about 20 percent more expensive remained. Our test results were very accurate and only slightly differed from each other. The result is decisively dependent on how accurate the measurement can be performed on the ear. When in doubt, several passes are necessary if as in our case the child is angry and fidgety. However, they became accustomed relatively quickly to the new instrument and the temperature values were trustworthy in the context of disease. To this extent I can criticism of some users here do not confirm, we would decide at any time for this small and handy tool.
