First of all, the measurement process itself is simple, switch on the appliance, plug in his ear, and wait until it beeps everything fine. Difficult it will only want to repeat the measurement, simply plug in the ear again and press the big button no longer works namely. As you press the buttons a few around until you have a state in which the repeated measurement works, a precise rule, I can not infer however. Or you from waiting until the unit turns off and begins again. The operating instructions as well as unhelpful, since (as already mentioned) only in English and includes terms that neither the Google Translator yet dict know (Ex .: "4. Measuring again: If measuring again, please unclinch the 'scan' button and wait for the '?' symbol to display, then press 'scan' button to measure again. "It's all about the above-mentioned new measurement, which" unclich "is, I could not figure out for the life. A question mark I could so far not even conjure up on's display ...)
Conclusion: Small device that does basically what it is supposed to weaknesses in the operation and inadequate manual. I can not comment on the accuracy of the measurement, but the results seem to me to be realistic.
Edit 25/04/2013: I have the thermometer now returned to the seller, it constantly showed Temeraturen about 37 degrees and not from person to person, it also showed significant differences in the measurement of the left and right ears, overall I think the measurements reliable.
In sum, two stars, one for the price, one of the relatively easy handling.
