I bought it and put it on paver in the middle of a kiddy pool full of sand and diatomaceous earth trying to coax these spoiled chickens into it. Squirrels got into the block and went thru it like you know what thru a goose. But they just ate the nuts and left the rest . Now after the storm and all that stuff is wet , it's working off down there I'm afraid the revenuers will show up any minute . LOL
