Scratch-prone

Here the quality of the actual product (protectors) with all kinds of accessories seems to be away deceived. Cloth map and "Dust-Removal-Sticker" are nice touches, but not really necessary - the gesture counts.

The actual protectors: When applying, if they are aligned to the bottom corners do not match the top cutouts for the camera, speaker and sensor match.
After application: Somehow sticky feel, but no fingerprints. Like all good therefore.
First time was in his pocket and pulled out again: Scratched. Lag with the keys in his pocket. If you do not seem to do - what you did but then a protective film ..?

So yes, you can use them, but you should be careful anyway, but then scratched just not the screen (Gorilla Glass 3 but seems stable) but "merely" the protector.
