Since the Wii does not support high definition, this cable will not really help you get a better picture.  Contrast ratios may be a bit better so your blacks are blacker but that is about it.  However, depending on your other equipment, for cable management purposes this may be just for you.  With my A/V receiver, what type of video you put in is the type that comes out.  Therefore when I have my computer output that is component going to my receiver then to my TV, I only need to change the receiver channel to swap over to the Wii instead of also having to change the TV too.  For this convience, it was worth the 7 dollars.
