Have the whole house equipped with these detectors. Compared to other manufacturers, the housing is very flat and worked "soft". This gives a pleasant visual impression (if you want to stick so because even a part of the ceiling, or must). The flashing LED I feel well in the bedroom not as disturbing, the detector should there perhaps but not necessarily be mounted directly over the bed so no one has to look supine constantly on it.
Had only a concern that the detectors are too flashy (we have dark Holzedecken) but after a few days we had the detectors again "forgotten".
Have the detectors mounted with magnetic disks. To date (since over 14 days) is still dropped no part.
