These controllers are impressive. They don't feel cheap like most cheaper controllers, plastics solid, I do agree with the other customer in that the d-pad feels a little stiff until it gets some use. Also it does not work in the Wii controller for those trying it for that.
Light, but very good quality plastic, seems solid. D-Pad was a bit stiff at first, but got much better after a few hours of playing. D-Pad is very precise, a lot better than the one on my Xbox 360 and Xbox One controllers. My only complaint would be that it is very hard plastic, makes your thumb hurt a bit after longer sessions of play, especially in fighting games. And the shoulder buttons don't feel as good as the original. Wireless reception is very good, tested 5 meters away with a closed door inbetween, still works. Input lag as low as my wireless Xbox controllers. Overall, very satisfied with it considering the low price. Would recommend this.
