So I bought one after seeing this thread and finally got it.
It's very obviously fake in person, the colors are wrong, the logos are missing, and the plastic is much lower quality with sharper edges and more creaking. The Analog sticks especially aren't even close, they're loose, the plastic grinds together, and they look as if they've been used for years. The Dpad is way stiffer than the original, the shoulder buttons are weirdly creaky and cheap feeling, but the face buttons are actually pretty alright.
But all that aside, it actually does work just fine. All the buttons work, the gyro works, it's detected as a pro controller, so cheapness aside it is a fully functional controller.
So I guess if you wanna pay half price for cheap plastic then sure, it's decent.
