I recently bought a wii and 3 knock off controllers from amazon. I have issues synching all four. I can easily get two but the other two don't work even when pressing the sync buttons at the same time, the wii one first and also resetting the wii. The weird thing is that the second controller seems to work even when i use a different knock off so i don't think the controller is broken, it just doesn't seem to like connecting # 3 & 4.
Thanks for your help!
Also another thing that is weird is if I leave the wii for a while and then come back it loses sync on the official nintendo one.
