Strong protections or too rigid

The quality is there, we must admit: scratch resistance, light loss of the limited screen, read the screen as possible even if it is not in front of the screen.
I found the pose a little tricky and I had to get back in several times to the rear screen.
Finally, the protection of the LCD screen (located on top of the device) is too rigid and did not manage to stick on the entire screen, which is slightly curved.
Note: when laying the protection of the rear screen, I mistakenly left a fingerprints on the sticky part. This track is part of herself after one day (magic!).
