I have had this feeder for three years now and it has suet nibbles and sunflowers seeds and nuts.
It's a free standing pole with a heavy stable base, it makes a mess on the ground but thats okay.
It's supposed to be squirrel proof but you can try to slow them down but never stop them entirely as they are very, very clever.
But who am I to chase such creatures away from my garden, weren't they all here before us?
