Small and almost invisible!

So we scoured the great selection of smoke detectors in the local market and then eventually got stuck at this part. One of the main reasons of our choice was just the size that is reduced to a minimum, it seems to me hardly possible, because something produce smaller.

The installation was relatively straightforward and easily.
At first I had doubts as to whether the LED function light could interfere with its blinking, because we also have a detector in the bedroom.
But I have to say that I ever consciously the light had at any of the device see flashing so that I even logged already doubts about whether the batteries may not be even are already empty.
Controls and behold ...... everything as it should be.

Conclusion: can a good buying decision that can save lives and this probably will not fall optically negative eye.
