we got 3 buster II decoys for christmas. Have only hunted with them for 1 day so far but already think they have made a differece. Not sure that it is making any difference on drawing in crows from a difference only because we have never had much problem with that anyways, but once thay get there they seem to hang around alot longer then before giving us more time to wait for the perfect shot. They seem to really focus on the buster and fly alot lower.
