I have the thermometer ordered blinded by the Amazon reviews. The beeping that normally indicates the end of measurement, is heard in this Themometer after about 30 sec. 35 °, it will be displayed. Substituting the measurement then about 10 minutes on, the display is at most 2/10 ° below what a calibrated thermometer measures. The measurement results vary - clearly you also do not know how long it is supposed to measure. Better to invest a few euros more and what reasonable Buy
