My friend will be posting video on his site soon.
He can't get good footage because the squirrels won't go near the feeder.

A friend of mine has invented a truly squirrel proof bird feeder that can be mounted to a tree trunk or a structure (no hanging).
It can also be refilled with one hand (no disassembly).

The outer ring with the large front baffle spins using a simple skateboard
wheel bearing as its only moving part (no batteries).
The ring moves when the squirrel steps on it and it spooks him out.
He can't get the food from underneath because of the baffle.

He's going to post video soon and I've seen the footage. It really does work.
It's a brilliant and simple design that solves a very frustrating issue in birdfeeding.

We work at the same place and I helped him cut the prototype parts
on our CNC machine during lunch breaks.
This is the last birdfeeder you'll ever need.
Hope this helps and I'd wish you luck but you're not going to need it
if you get one these feeders.
