I have had a problem playing Super Smash Bros Brawl on my Wii console, and the Nintendo site told me this problem was probably due to a dirty lens. As my warranty had run out on my Wii, I did not want to send it away for repairs, so cleaning the lens was the way to go.
I soon realised that ordinary disc cleaners would not work on the Wii, as the Wii only spins discs it recognises as games, and spinning is the way most cleaners work. So when I saw this product, and saw that it was an official Nintendo product, I decided to buy it.
This product has worked perfectly for me as one use has done the trick and my game now plays, this is a very viable solution for others suffering the same problem. The instructions are very clear and exact, so you know precisely what to do, and there is no room for error if you follow them.
