This makes them well provides better protection than the official, since the edges are better protected in a case.
Speaking of edges: if you push a little at the edges, it creaks a little. I fear that by the edges of the phone are then certainly worn.
But what most bothers me: If you have the cover upside down for a while, because you are surfing the Internet, playing or whatever else - and you want to close the phone again, the lid opens again on its own.
And one more point to Quick Circle function, although does not directly concern this product, but somehow belongs to and can contribute to the purchasing decision:
With Quick Circle can take pictures without the cover to open. Actually, very practical, but that meant that I have a lot of pictures taken of my pants coffers. I have this function then from the Quick Menu Circle.
