At first I was quite happy with the weather station, if you take it apart, that has the outside thermometer display always 1-2 degrees warmer than it actually was (counter measurement with three other thermometers) Since a few days, however, the external sensor is spinning completely. Displays eg 2 degrees temperature whopping 13 degrees to :-) Partly it fails completely, although he is only 30 cm of the station (window in between). Here, a life of their own seems to have developed. After the manufacturer unfortunately could not offer acceptable solution, fortunately, Amazon has taken the item back and refund the purchase price. So 5 stars for Amazon, 2 stars for device and manufacturer.
