The guitar feels a little different than the official one. The spacing between the buttons isn't exactly the same and the opposite side is rounded. That being said, this has worked great for me. I didn't want to pay full price for another official guitar after having already spent so much to get the game with my first guitar, so I went with this and I am satisfied with my purchase. It has allowed me to play with two people and I have not had any problems with it. If you and all your friends are hardcore guitar hero players, then go for the official, but if you are a casual gamer or don't play on expert, this is a great way to allow two people to play without spending too much extra money.
