I bought this case to use with my 8bitdo controllers. I can fit 2 controllers in it, one for me and one for my girlfriend when we go out of town. I set up a Raspberry Pi as a RetroPi for gaming and everything is small enough to fit in a small backpack. This case protects my controllers from scratches and keeps my joysticks safe and healthy. You can't ask for more from the case, it even looks cool as a large controller
