Unwrapped, turned, put his ear and measured in a second temperature. It was promised and it works well. If it were not for the measured up to half a degree differences in the measurements. Since then, after the first measurement with, for example, 37.2 degrees in the subsequent second measurement, 36.7 degrees. That's for this price then too imprecise. Too bad, you could certainly do better. Would it therefore not buy again. Therefore no real buy recommendation from me.
