BUT: As so often, the devil is in the details. After a fall of only 30 cm higher functioned no longer one of the front shoulder buttons. Opening the controller let the problem quickly realize: The front shoulder buttons are stopped by tiny plastic "suppository" (about 1 mm long, and half as much in diameter, one end exposed) as soon as they hit the button. These are of course canceled. As soon as you now presses the button, each time the button is slowly but surely bent inside down until the shoulder button and the button at some point pass each other. The plastic cones are really so small that I did not find it again, despite a long search. So I tried to largely avoid and to act by a cumbersome processing only with the intact key this key. A few weeks later, the same error is now, unfortunately, at this key occurred, this time without application of force due to dropping or the like. The plastic has just given way and now both buttons function limited only to a limited and temporary. Every few days I need to open to the holder of the key again to turn the shoulder button down the controller.
Very very annoying, but should a manufacturer like Logitech, with years of experience in the field of input devices, expect that the controller sooner or later "fall off" or a grown man unconsciously a harder pressure on the keys exerts, as a child.
Therefore unfortunately not buy rating on an otherwise excellent game pad.
