In contrast to the perfect cover a large Silikonflansch stands at the back - perfect for a flanged touchscreen with large bright sunlight protection. The can be separated naturally. But the recess at the lens is a diamond with plenty of space under the edges with me. I have my GoPro 3+ in protective housing, mind you, so there is no danger for the Cam. The Seitenausparung for the WiFi button is also cut out dirty, but does not affect the function. For a handful of euros hardly a will complain and not send it back, but really useful these wobbly fitting silicone holder is unfortunately not. Dirt will penetrate everywhere among the recesses abundant between silicone sleeve and underwater housing, if it falls into the puddle times. The cushioning is just ok. But there the second star.
