As for the joystick, it was indeed an official, it is the same as the one you can find in stores like FNAC, E.LECLERC ... but at a much lower price .. . (Price in most stores: about 45 while it is proposed here for about 30 !!!!!)
Tip: If you want to buy a joystick: MORE PLEASE !!!!!!!! BUY ON THE AMAZON !!!! Please write SAVINGS !!!!
In addition to that price you'll get a wireless controller and official ... What you ask for? :-)
Enjoy :)
