Amazon Review May 16, 2014
Squirrels are definitely baffled by this device when they crawl up the pole. It's funny to watch their little brains trying to work out a solution which they never do. They finally resign themselves to the ground. Then the next generation comes along for a repeat. I did have one very clever squirrel one time that chewed through the plastic collar that keeps the thing in place. Mission accomplished. But it was a baffler I bought at the hardware store. They have yet to breach this one. Do not put near trees that they can jump from though. I think it's recommended 4-5 feet away.
