Who still has a good ear, should take more distance from this smoke detector be if he, for example in the bedroom "only" is to be installed about four feet away from the bed. That part in itself already looks good, compared to most other, but the most important purchase aspect was the fairly small size. What unfortunately bother me seriously, is the already frequently described "click" in 10-second intervals, especially when going to sleep, when the ambient noise is now time to an absolute minimum, is the permanent "click" for me unfortunately very strongly perceptible, even with a peaceful setting in the living room I hear the sound from the hallway. Most guests aged 40+ hear the sound probably not, but until then I have a few years time. For this reason, I now make my way to look for an alternative.
Very bad: Packaging, shipping, design and size is all great - the volume in case of fire is more than adequate - but the constant "click" is not tolerable for me.
