Bests & Worsts Reviews from Amazon

What can I say. Installed 3 of these a couple months ago and the pigeons pay absolutely no attention to them - none! Spent a whole afternoon cleaning all the pigeon nest material and bird poop off our Phoenix homes roof and installed these 3 devices and have been thoroughly disappointed. While laying here in bed writing this review at 0430, I can here the little bastards moving around, clucking and minding their next while I type. Very disappointed.
