Very cheap and relient item.
I am surprised as sensitive it is.
I like it and would order more for other projects involved motion detection.
No cons at all.
May be one - you have to ajust two rotating resistors to have time and sensitive you need.
But in fatc I think this is not cons but rather pros beause you cand ajusta it to you project precisely.
It has matrix of hexagonal pattern on it.
You do not see that on the foto but in fact this is hexagonal structure on it.
For me this is nice and no cons at all but look differenct from picture be aware of it.
