Hung this feeder up a few days ago and so far it's been great. The birds love it and I've seen a good variety. Just watched a squirrel climb up and try to eat from it and he was repeatedly stumped. I'm worried that a smaller squirrel or chipmunk might have better luck, though; I have it on the most sensitive setting, but it still barely closed when the squirrel pulled on it. But of course it's a fine line between being too sensitive so birds can't sit on it, and not sensitive enough so that squirrels can get to it. For now, though, the birds are enjoying it and the squirrels have been kept away!
