I wanted to buy guitar hero for my Wii, but didn't want the latest release. So after some reviewing I found out you could buy any game and the guitars separately. Wasn't really sure about the differences between the guitars, but went for this one and it's great! Now I'm not a techy that knows much about this sort of thing, but it's an official Wii product and it works. And the game keeps telling me I rock so I love it!
