My Wii control original burned, I don't know why this happened! Anyway, I decided to buy a alternative control Chinese to test and it worked great.
He came to Silicon dust cap, that is not original.
Has everything you need in a Wii controller, including the Motion Sensor, There was no attachment in the Original Wii that improves the resolution of the control.
Features including the entry for Wii NunChuck. The version I bought I haven't been with the NunChunk and is a little cheaper.
All the same the original, at least so far!
Worked perfectly. Played Mario Kart and Ping Pong, the best Wii games, and it all worked out! I leave below link for both products, with and without the NumChuck:
