Have just received the controller after a long wait. Because they come from China, however, the delivery costs are relatively low, they are obviously by ship. But if you can wait no problem. I bought it to connect it to the new Wii U. An old Wii I did not, so can not say whether the controller function there. On the Wii U at any rate the controllers are not a problem. Go sign up on the Wii Menu to controller, press the corresponding button on the controller and wait a few seconds. Impatient as I think after about 2 seconds, the controller will not work and are already thinking about returning to. However, the bonding takes hiss Controller and Wii U obviously up to 10 seconds. If one waits that the device is recognized without difficulty and you can control the Wii U normal about it. Even on and off the Wii U goes smoothly. Lack Wii MotionPlus controller relies solely on the natural infrared LED strip, which is not quite as accurate. But this is a fundamental problem of the controller and has nothing to do with the actual product. As an additional controller for the Wii U, the device is thus fully OK.
Delivered the Wii Remote incl. A silicone cover and the Nunchuk controller. The Nunchuk connects to the Wii Remote via a cable. The connector makes up a fairly reliable impression. Negative Ratings bez. poor contacts I can not understand in my device: here nothing wobbles, the plug is rock solid and there are no dropouts. Power is supplied via standard AA batteries which are not included. Optimally, you use batteries.
The extent to which the device is used as a complete replacement for the primary controller to a Wii, I can not say. As a secondary controller for the Wii U, I can issue a strong buy recommendation.
