I am always skeptical when buying other manufacturers items for name brand things such as Nyko for Wii. I didn't really want to pay out a lot of money for a nunchuck and this had great reviews so I decided to give it a try. I was not disappointed at all. The kama fits nicely in hand, lip on the bottom button helps you know which is the "z" button, and it's function is just as great as the Wii's nunchuck. Movement on screen is fluid. I am very happy with this purchase and I plan on getting 2 more for the other Wii-motes for when we all play.
