User Summary
"Despite the way it is marketed, this controller is not an alternative to the Wii U Pro Controller. Rather, it combines the functionality of a Wii Remote, Wii Motion Plus, and a Classic Controller into a single wireless rechargeable controller. It is recognized by Wii and Wii U systems as either a Wii Remote or as a Classic Controller, depending on the setting of a switch on the back of the controller. It will not function as a Pro Controller in Wii U games."
