Query: Squirrels cannot get in, but they can knock it down

THis is a nice feeder. If your squirrels aren't particularly aggressive it might work for you. However, they easily can knock it off the pole/branch and eat the seed off the ground. Another issue I have is with moisture and sometimes FUR (YUCK) getting in the feeder holes, thus defeating the whole purpose. I was too frustrated & had to throw it away. Also, one time the top wasn't secure and the squirrel literally crawled into the tube. I saw him eating and was just amazed at his feat. Hand to God.
