Before I�begin, let me just say that the Nunchuk that I received works fine (so far).However, bear in mind that the source you receive your Nunchuk from will determine just how ""genuine"" it is. When I ordered mine, it was through a third-party vendor named ""Pegasus Toys And Games"" for $16.99. I see that, at the time of this posting, it is a different vendor. I am always concerned about getting genuine Nintendo accessories. In this case, I don't believe that is what I received. I won't go into too many specific details, but here's what I did:I compared my original Nunchuk that shipped in the box with the console. If it was a true genuine product, everything should appear exactly the same. However, I found subtle to great differences in multiple areas with the controller I received. Take the cord as an example. One, there is a cable marking that identifies the quality/standards of the cable on the Nunchuk that I ordered; the original one is unmarked. Also, where the cable meets the base of the Nunchuk, there is a shorter length of the flexible section than on the original. Other differences, like the texture of the joystick and the pins inside the connector, make it just seem cheaper. Even the little book that comes in the box seems like it is printed on cheaper paper (not glossy like other manuals, but still has the ""Nintendo seal"" that ""proves"" its authenticity).Though it has been working fine so far, I am disappointed that it is not quite the same thing. Yes, you can buy cheaper third-party manufactured controllers, but I was hoping to pay for the real deal. You are better off purchasing this type of thing from a big name retailer or department store (and paying the $19.99 plus tax rather than trying to save a few bucks).
