I use to run the critter and had mixed results with it. I had a lot more birds dive bombing it them yotes locking in on it. I have been thinking alot about getting the blackjack. I don't care for the jack in the box much either. I don't like the movements it makes. Right now If I am packing a decoy its the critter by edge. Works pretty good but once again just a noraml motion. The black jack is crazy and has a lot more jerky movements and not all the same movements.
