Query: NOT SQUIRREL PROOF!

I'm not sure if this is supposed to be a squirrel proof feeder - it looks like one, but it isn't. Squirrels can lift the lid, climb in and eat all they want. I guess it's a nice bird feeder (but so is a paper cup). In my opinion, a bird feeder is a squirrel feeder unless it's properly designed.
