Bests & Worsts Reviews from Amazon

They work. Plain and simple. But be aware that if wind blows one of these down and a bird is unfortunate enough to land on it? They can't get off!! A poor bird landed on mine and he was stuck for who knows how long!! He tore his tail feathers off trying to get off and they bled, I got him off easy enough, managed to unruffle his wing feathers good enough and he was able to fly away but I was horrified by his pain and anguish. I still feel terrible that I was unaware these are sticky enough to trap a bird. I had secured one to a feed a cage with the twist ties but when the blew it twisted the board around so many times it broke away and landed on the grass under my bird feeder. I will secure these differently from now on because the are a danger to small animals. That was certainly the last thing I expected to see. Update, I finally used my big block bird feeder box to hang these safely where they lose no danger to the birds or other small wildlife. They can't blow down now! We had 70 mile an hour winds yesterday. That's unusual, the normal storm winds blew them off the ties last time. It was heartbreaking to see that little bird stuck on these, I couldn't risk that again. These work!
