I ordered the thermometer for the work, because it has annoyed me never to know how hot it is inside and outside :)) In a comparison with an expensive weather station only minimal differences of +/- 1 ° C resulted. That's for the price in Ordung. The only drawback: The battery is quite expensive in the new acquisition, because it is a CR2032. That makes up for TFA but by enclose such a battery equals the supply.
