In about two days my squirrels had figured out this little chestnut. They hung upside down, marked the feeder and used their paws to scoop out the seeds. This was Birdfeeder Cracking 101 for them. On my model the top wasn't even secured, which might have been a problem if the front door wasn't wide open. This ended up in the trash fast, where it probably will for you if there's any squirrels within a square mile or so of your house. Do what I did and buy the Heritage feeder instead, still working like a charm after 6 months: Heritage Farms Absolute II Squirrel Proof Bird Feeder.
