I didn't realize that this wasn't the official controller by Nintendo until after I ordered it. It was $10 cheaper than the normal one so I thought I was getting a deal. But I waited until I got it today to give it a spin.
It's alright, but it isn't as good as the normal controller. The Wii logo is missing of course, and some of the buttons aren't as comfortable like they are on the normal one. It is just an attempt at a look-a-like, and I am surprised that Nintendo hasn't realized this auction yet and ended it (only because it probably violates some copyright rules).
I ordered a normal classic controller pro and am returning this one soon.
