I only used the outer case because the buttons are unlabeled and it would look too cliche to use them all. Also, the plastic around the buttons is pretty dirty and I doubt they will work properly. The case fits very well. The only problem I had was that the panels on the sides of the handlebars didn't match up exactly. This creates a thin gap on both handles. It really worries me but luckily it's for my daughter and she loves her pink controller.
