When Klappmechnismus I was skeptical at first, whether it is not too much hampered. In practice, however, this is only relevant when taking pictures and I got used to it quickly.
Since it is only a protection for the display, the S3 is not as fat as in other cases, but the cover is still unprotected. Logically.
Unfortunately has after 2 weeks use of rubberized rim run slowly replaced by the cover and the cover now looks not so nice.
The notification window is obstructed and you can see it no longer, or only a very slight glow. In practice, this has so far not been a problem for me but could be more important for others.
The volume buttons are hidden, but can be in principle, even with closed cover use. Is more of a Überungssache, I think. For me it was no problem.
Would I Flip Cover buy again? Unfortunately not, because the narrow border around the cover a real weak point and I do not like it, it looks like a cover of dingy. Maybe I've just the problem. But otherwise I like the cover much, it would have also like to have other colors, for example green.
For ideas and design give it 5 stars.
The quality I prefer from 2 star.
