I bought this for £35 - although there are plenty of gun housings for under £10, this one is a cut above the rest. It is not immediately apparent from the picture, but the move controller is actually USB connected to shooter, so unlike the other controllers the buttons are not mechanically connected via some crude spring attachment. The shooter houses its own move and trigger buttons as well as triangle and square buttons on either side of the trigger. Underneath is a reload button and the white part which houses the navigation controller can also be used for reloading by pumping towards you.
I was initially confused with the omission of X and circle button but all became clear once I bought the optional navigation controller, as that is where they are.
The controller is surprisingly weighty so this takes some getting used to, as does the position of the navigation controller, but after some practice, all is good :-)
I would have given this 5 stars, but dropped a point as you need to remove the move contoller from the housing to charge it. Seems obvious to have had an external charging point. Also it doesn't shoot real bullets.
