Wildlife Sciences Songbird Treats 13 Oz. Woodpecker Seed Tower 921

These bells do not last a day with the hangers they have used. I have squirrels that can climb down the wire used to hang these bells on tree. The hanger they use does not go the whole way through the bell to the bottom. It only goes to about the middle and comes out so easily when the darn squirrels land on it. I have bought other bells and they are much more secure. Not sure why they would not put the holder all the way through to the bottom of bell??? Won't buy these again.
