I have been trying (and failing) for many years to find a wild bird feeder that the squirrels in my backyard can't feed from. I've found one. Yours! My squirrels have chewed through my porch screen, Plexiglas, heavy-duty plastic, and every material you can imagine. They have hung upside down & fished the seed out with their extended front paws. They've enlarged the openings on feeders with Plexiglas tubes and spring-load feeding perches. Yours is the only one they haven't been able to figure out. They've finally given up & I am now able to feed the birds with my bird feeder. Thank you.
