Squirrel-B-Gone™ Feeder Review
Not quite right

Reviewer Comments: I bought one of these from you last year. For a number of months it worked fine and no squirrels were able to get in. Then they worked out the details and would pry off the cap which unhooked the little springs and allowed them access. I rehooked the springs and put the cover back on a number of times but they always got back into it. I figure it is because our squirrels are more intelligent than yours. After all, we do have Harvard, MIT….(I have ranked it unstable because of the propensity for the springs to come off when challenged by smart squirrels.)

I live in the Pacific Northwest (Silverdale Washington) We have the small brown squirrels that are much smaller and lighter than the grey squirrels.
I set the springs to the lowest setting allowed, and it was still penetrated by these little brown guys. Their weight allowed a small opening in the feeding holes, just enough to chew out the plastic below the feeding hole and “Chow Down” as if there was no deterrent in place. They also pried up one small leaf in the flower that covers the feeding hole. By the way this all took place in two hours after hanging it up in the tree.
