Our smoke alarms have annoyed almost every 6 months ...

Let's see if these parts keep their promise. I will (if still goes) to update this report and publish the results. We have several GIRA detectors with radio modules in use and even the Duracell have kept well below one year. The buyers of some mentioned minimally larger design interferes not in the detectors. If I
could not have read, I would not notice it.

Today is Christmas Eve, therefore, exceptionally, to take this opportunity once beautiful Christmas greetings!
