I have this protective sleeve for some time in use and you can see that it also. The first signs of wear can be seen, but the Habtik can not touch. At the corners of the white plastic shines through and in the recess of the "On / Off button" the material was too thin. Even aluminum had since broken away with the time well. This fatigue but I have expected. Nevertheless, I would probably buy the shell again, if I did not find anything comparable. The cover makes nähmlich what they should. A little protection against impact damage. the Nexus has had several falls behind him, but no optical or functional damage.
