Although it is written "WiiU" on the package, it is indeed a repeat of the good old GameCube controller, with a new logo and an extra long cable (in m 3). Basically if you already have a Gamecube controller; no need to buy this one (except for collectors of course). This controller is compatible with: gamecube, wii (see adapter for generations> 2nd) and WiiU (idem, adapter required)
It works great after I not only put 5 stars because sears look a difficult hair, but from memory they were already like that back then!
