Our 1 TFA 35 (not via Amazon purchased) depends now 3 years quietly on the wall, apart from the cyclical timely battery change times, but to have crashed without ever, yet is now defective. The weather forecast does not work, because the air pressure measurement is faulty. Since the outdoor sensor is still intact, so I bought a new device (Amazon), which I still have to get a 2 compatible external sensor.
The new device was put into operation without any complications. A long-term experience I have of course of the new device not yet. However, I am now careful with a rating. Perhaps the new device even comes back for 3 years. Carefully, I rate it with 3 stars. I am happy to send even a comment at a later date.
