content: I am sorry that I ever bought this thing, it is the most annoying "toy" I have ever bought. No matter where I put it or how I adjust it, it goes off all night long. This would be a great gadget in theory if we lived in an animal free (No squirrels) and bug free (no flying beetles, moths & etc.) world but seeing how that is not the case, it's really not good for anyone. Even the shadows of people and cars set this thing off. I thank god that I didn't buy two alert systems as I originally planned.
