I have 2 of these motion detectors in use - 1 time for my storeroom as "light switch" and as a light switch my display case in the entrance area. The adjustment at the start is a small "fumbling" until you reach the desired length - but he does good his service, even if he can not have a perfect angle of incidence locally conditionally.
I highly recommend this unit! Of course, for the sake of appearance, there are devices that can be better "hide", but this does not always play a role.
For this price, definitely 5 star - I've already expensive detectors in much worse Quallität seen!
