Query: Squirrels are smarter than the makers of this feeder.

No, maybe squirrels can't get inside the feeder, but they don't have to. All they have to do is shake it or set it to swinging, and seed goes all over the place. Then they take what seeds they want out of the resulting mess and leave the rest to rot. They can trash a feeder's worth of seed within a week. I'll be looking for yet another feeder as soon as I can afford it.
