Picked this up along with a Move and Nav controller during that "50% off Move" sale that Gamestop had about a month ago.
I'm not a big fan of shooters or of motion control, so pairing this with KZ3 was an entirely new experience for me. At half price---I liked it. The gun's controls are laid out really well, and it feels natural after a while.
One big difference between this and similar controllers is the digital inputs. The Move actually plugs into the Sharp Shooter via its USB port, so trigger inputs are instantaneous.
