It actually works. The directions are easy to read and the unit gives you a loot of options. I can only talk about the one i bought to keep crows, blackbirds, ravens and grackles away. I would get flocks of them since i feed tjhe birds and they would take-over the feeders. Now a few come in, but leave very quickly. Works great!
