But what's that bin's !!!!

I bought 2 sensors without problem etc ... after a month, I toast bread (too), the BIP detector.
Hopefully I tell myself: it works !!!
However, since this first detection, it sounds anytime, so I change the battery ..
well ... nothing there ... he ends up in the trash.

I redeemed another .. !!! even cares (I must change my grillle as bread ...)

So if I understand correctly, if it detects only time the smoke, it is good for the trash !!!

it is expensive mess detector ... 15 20 eur each time.

I just see BTW ...
