Customer Comment: "Just had to tell you. Hung wb-wb-8 Squirrel Proof Feeder and within hours had a furry one try to dine. The action of this food robber was great as promised. He (or she) went down the hanger and made contact, did a double flip and grabbed for tree branches. Several others have tried with like results. After only four days I see them stop in the tree, examine the feeder and go on their way. This is one poduct that lives up to what is promised. The savings in food is worth the price of the feeder, not mention the entertainment value. Thanks for a great product."
