[quote name='SoulReaver']I'm an idiot and can't figure out how to put on the new straps and remove the old ones.[/quote]
Actually, it seems quite a few people I know didn't know what to do either.
It's too much work to try and salvage the old strap; just cut it off the remote.
Then, pinch the string on the new cord together (pinched looks like: " === " ) and slide it through the holes on the wiimote. Now, you should have the string going through both holes and back into its loop shape " O " . Then, take the entire strap, and slide it through the string loop. The string will come down the strap, and then you can pull the string tightly into a knot on the wiimote.
Hope that helped, though typing it is tough to do. You could always look online for a diagram; I'm sure there's one somewhere.
[quote name='daroga']This is weird.
While I was visiting family over Christmas week, my 2 replacement straps came in the mail.
Then yesterday, another package came from Nintendo with 2 more straps. Anyone else get 2 separate shipments?[/quote]
Same thing happened to me, though I got both my packages on the same day. I guess I just assumed everyone saying they got extra straps got two packages.
