Possession of 2 Xbox One controller, both of us had to send in even at Microsoft !!! Since the left analog stick has been set every time and no longer controlled by the left! Inferior quality! My 360 Controller ran without quirks and years! Too bad that Microsoft has saved in the materials. Otherwise, the controller is look beautiful! Fun guaranteed! Is clean in hand. The keys feel better than the previous model. And I personally think it's also lighter than the previous model!
