It can go, but ...

Detector that worked great in the beginning when I installed it.
Now, sometimes, in certain occasion, it is less sensitive to motion and thus slower to turn on.
I do not know why, but I often have to tighten the bulb that needs it.
Maybe it comes from the bulb I use, with special lighting and a bit heavier than a conventional light bulb?
I have doubts about the life of the detector and I remain vigilant.
I think the price is not more beneficial, because I have seen this item cheaper elsewhere slightly (-20%).
