I have had a Wii for a few years now, but up until buying this cable, it was connected to the tv using the original composite cable. This wasn't so much of a problem on our old CRT TV, but on our newer flat screen, the quality wasn't as good as I would have liked.
After doing a bit of research, I found this cable. Having now tried it, it makes such a difference compared to the original cable. All I needed to change was the display type in the settings, to help fine tune the quality. If I every need to replace the cable again, I'm going for this one.
