When I first got this birdfeeder, it cut my birdfeed bill by more than half. The squirrels had been draining my previous feeder almost daily. The feeder survived squirrels in 3 different states over the course of our various moves and did a wonderful job before finally meeting its end during a 60 mph wind gust. I obviously hadn't fastened it well enough and it crashed into a boulder on its way down. It performed so well, however, I'm getting another!
