Adds to the wii
I got one of these to give a little more to my wii and it does just that the only thing is the wii has to be switched on but that's ok too.
It certainly adds a little something to your wii console it used instead of the stand that comes with the wii so it's easy to set up.
It runs off the usb ports on the back of the wii but comes with another usb slot of it's own so you don't lose out that all.
All and all brillant product and official too.
