So yes, when I put the batteries, the controller was not recognized by the Wii. FYI, you have to press a red button on the controller, located in the battery compartment. Then all the diodes will start blinking. Meanwhile, you have to press a red button on the console. This one is behind a small door above (or below it depends how one stands) of the disk drive. So I pressed 2 or 3 seconds on the button for the flashing LEDs on the controller and O miracle, a small hand appeared.
Against by, after one hour, the joystick was no longer detected. So I remove and replace the batteries from the controller and it works.
The product itself does not breathe the high end but is quite correct. We will see for the life but anyway my dog is going to eat at the first opportunity, I think I can not evaluate it properly ...
Cordially
