Title: Very stupid machine
Review: This product does what it claims to, to a first approximation, but the motion sensor is very stupid. Towards the aggressive end of its sensitivity adjustment it goes off repeatedly into wind or when the pattern of shadows changes fast (perhaps the sun comes out from behind a cloud), but on the same setting it will let deer mosey to within one meter, straight ahead, before it will turn on. If the area you have to protect is tiny (a few square meters) then it's great. Deer jump a mile high when they're standing so close. But for larger areas it is nigh-useless.
