well, try to play a game n see ba .. thats how i tested. try sensor bar , wiimote , nun chunk, game loading, got wii channel or not, and if possible try wifi.

And if you're going to get another pair of wiimote n nun chunk then i suggest u search for the thread where the user posted the fake wiimote n nun chunk. Dun get cheated by buying fake ones with ori price.

Well, if you buy from reputable seller in lowyat forum then it would be better ba. Your choice anyway
