Summary: Nowhere in the description of Rock Band did it mention that it was not compatible with some Guitar Hero devices. Instead, the advertising implies that it will work with WII Guitar Hero. After it was delivered to my house, I opened it with enthusiasm. After about an hour of trying, I finally went to the web and found out that it was not compatible at all! I will need to buy another guitar that is not wireless in order for it to work with my WII. I feel cheated!
