This controller is the unofficial nes classic 9 foot long cable, keep in mind all is not what it seems.
The code book has multiple languages, English and french, keep in mind it only has the nes classic games, and it has very few cheats, and more or less a descriptions of games. Many of the images look like fan-art images tooken from the internet.
As for the controller, the 2 nes red buttons feel nes-like, no problem with them but the turbo has a switch
Turbo B & A, so it is either on A or B, meaning you must switch back and forth for it, but there is also 2 addition buttons above the red buttons that is hard to see in any of the pictures. the turbo button which presses which ever button is selected in the turbo switch, and the B+A button that simulates both B & A being pressed at the sametime. Now I don't know any use for this but the turbo system on the controller is rather annoying during mid-gameplay. In other words I would just ignore the switch, and two additional buttons as they bring nothing to the table except in shoot'em ups.
As for the dpad, it is not a nes-like dpad but a single piece that is clicky unlike the red-buttons it does not feel like the nes controller, but rather a clone controller.
The select and start how ever do not feel exactly like nes controllers but close enough to say meh they are hardily used in most games so alwell it is better than most clone controllers.
I would how ever recomend this controller for its length of cable. It makes it fun to play your nes and classic games on your wii, wiiu, and nes classic console.
Interworks and Emio did a good job on this to make it look very close to the nes controller, and feel similar to it but it still could have a few improvements.
