Mine came with a cone, but it didn't help too much because the squirrels could jump across from a nearby tree and land on the cone. They then tried to climb up the pole and tried to reach across to the hanging feeders but couldn't quite reach. After a few days of attempts, they just gave up. I removed the cone then and I haven't seen any squirrels trying their luck since, not even trying to climb up the central pole as they just seem to slide down it again!That's quite similar, but it lacked the cone, so I made one today.
