No, it isn't. It's an official Nintendo product. And it works perfectly. I haven't had any problems with mine at all.

I hate this state. I hate it so very, very much.

So, I actually had to pick up one of these controllers yesterday. Metroid Prime finally came in at KMart, and the controller was part of their "KMart Exclusive" thing. I was okay with it though, considering I wasn't willing to drive two hours to get my copy of the game this time. And the controller is actually really cool too. Now I have less cords getting all tangled in front of my TV. The only part I don't like is that in order to save battery power, the thing doesn't have a rumble function. Oh well, it's not really that big a deal anyway.
