The device works very well. There is a but by the advertising message "Satellite-based wireless weather station" vorgegaugelt that the data is transferred directly from the satellite to the weather station. This is of course not so. This weather station has as much to do with a satellite transmission as a cows can lay eggs, namely garnix. The data comes in reality from a pager network. This pager network was previously operated by Deutsche Telekom as Skyper network and is now owned by the company e * Message operates and does not send via satellite, but in the 70 cm band at 465 MHz. Since time does not come by the time signal DCF77 Eder, but from the data stream of e * Message is to read, it is not very accurate. There may be deviations of up to 2 minutes. What is no longer a state of the art at the present time. Otherwise, the weather station works very well, if you good reception to one of the 800 e * Message has Sendeanalge. But the manufacturer should quickly adjust the false advertising claim to the "" Satellite-based wireless weather station ". In my opinion the only on the packaging is to sell more units. Desswegen only 3 stars. Without this statement, the weather station deserves 5 stars.
