We have a ninja squirrel that ALWAYS get in our bird feeder including the “squirrel proof” ones. But this feeder has stopped his game! This feeder was pretty easy to put together, other than the cap that goes on the end that the feeder itself attaches too. I had to fight with it to get it on and to get the feeder to slide down on. But its very easy to fill and keep clean. I was a little confused on the plastic divider that goes inside because it was loose, but it’s just to make sure the feed goes down to the holes. My little song birds love it because they don’t have to hang on for dear life like they do our other 2 hanging ones. Also to add this thing is sturdy, we had a wind storm the night I put it out and it didn’t budge at all. It’s a great feeder!
