Perky Pet Brown Squirrel-Be-Gone III Wild Bird Tube Feeder - 8 lb Capacity

After reading the problems a few of the other reviewers had, I suggest reading the instructions; they may get thrown out with the box. I have had excellent results; it really works IF the springs are correctly attached and all attached in the same way. There are FOUR holes to use; your choice. Oh, and a tray would allow squirrels to defeat the mechanism. I do think the manufacturer should make the instructions a full size sheet of paper and much clearer. My three feeders save me money in seed and are well worth their cost. They hang outside a large window under an overhang, and my computer is right at the window. I use either Morning Song regular or the Gourmet; lots of birds, even white breasted nuthatches that feed upside down! Wonderful and practical feeders. If squirrels keep bothering the feeder, shake some cayenne red pepper on the TOP of the feeder; they won't be back. It takes a couple weeks for the birds to find and get used to the feeder.
