It could well be there are problems if they are simply thrown in place.
But that can be said for most things.

I dont believe that's the problem at all. Doors are prone to move in
alignment over time, and gusts of wind can bend them. Both resulted in
false alarms.

If a gust of wind moves a door enough to trigger a reed switch hardly
worth having that door let alone the alarm.

Of course if a door or window no longer closes properly so the reed is
'on', a timely reminder to sort it.
