These Wii Remote Straps are awesome!!! You don't have to use them on Wii Remotes, but on any gadget (I used the Green one on my 3DS).
There's 4 of them, so you can share them between the family (or have his and hers Wii Remotes). although their could be another pack with four different colours (say yellow,red,purple , & black). The Quality of them is good as well, and the Clasp is quite sturdy.
I ordered mine and they took 4 working days to come which is very reasonable (as its free P&P). They also are a reasonable price at 3.99.
Overall, you should get these not to use on your Wii, but for any electronic device that you might need a Strap for.
