Hans-Uwe Elsner
Very good weather console

The WS3900 is to replace my first station, the WS2910, because I want to use more sensors.
I am very satisfied with the new WS3900.
Good operation and very good readability.
The only thing I miss are the trend arrows, e.g. for temperatures, air pressure and humidity.

Beautiful Console!
