Bests & Worsts Reviews from Amazon

We had a big robin that kept smacking into our living room window each morning again, and again, and again, and again. He also would bang into both of our cars parked under our car port again, and again, and again. We could tell because every day we'd go out to our cars and see his/her flutter marks all over the west facing side windows of our cars. He/she also pooped all over the west side of our cars. Not just a little poop, but a massive amount of poop. Each time we'd go out to our car we'd have to clean it off. Even if we'd only been gone in the house to get something we'd forgot, we'd come back out to cars covered in poop. So we bought this and hung a strip from the eve and carport above each window and instantly no more flutter marks on our windows and no more poop everywhere. Success. If you have a deranged bird banging on your windows and pooping all over your stuff, I'd highly recommend this product.
