The quality with this unit isn't quite that of an original xBox controller. But, it IS a good quality controller, and functions quite well. Especially, for it's price. The internal batteries in these units last quite a while, per charge. We've done a couple of "all-nighters" with them, so far. And, they've stayed in the fight.
I really like the quality of the buttons, and gimbles, though. Not typical, short lived, hit-or-miss, cheap Chinese examples. Controls are fairly precise, and responsive.
I don't recommend throwing it, and expecting it's cooperation, afterward. But, that said, I consider the pair of these that I purchased, a very good value, for my money.
