I've had similar type feeders for years but never any this sturdy. I love it! However, in the first four days it hung outside the squirrels were able to pop the top somehow. I was absolutely sure it was closed properly and the spring mechanism was working, but those little suckers got in anyway. Chewed the plastic square insides and the yellow center stem to the point of breaking. Hopefully I'll be able to replace it. Other than that first episode it's been great. I do now have a DYI squirrel baffle on it.
