I bought 2 to complete the 2 single Wii-mote controllers of my children. Perfect function, recognized by the console Wii U. It actually are "Wii Motion Plus" official but without blister and delivered in small sachets, which may explain the price more than correct (9.90 Euros). In addition, for those who are wondering, they work very well with branded controllers other than Nintendo. Otherwise, delivery time and parcel OK;
