Fits to any GoPro camera,

I've just received the item from China, a week after it was ordered. The bolt for the screw comes loose but a drop of glue do the magic.
It fits to any GoPro camera and it looks just as the original. The plastic looks a bit cheap though but it should do the work if you are gentle with it.
