Accuracy barometer crying

"Measuring range Barometer 700 to 1050Mb / hPa
Barometer Accuracy +/- 7 Mb / hpa "

1- We should say 'millibar' or 'mbar', not 'Mb'. This error is constant regardless of the language of the manual.
2 Worse, the precision of 7 millibars !!!!! While atmospheric pressure usually ranges between 1000 and 1030 millibars.

I confirm the barometer malfunctioning. In fact, this sensor is a temperature sensor + humidity. The barometer is a joke.

Really disappointed because I had taken this probe only for the barometer function.
