Negatives:
Why must be on the front above the left side of a hole in the film? There is only the distance sensor. Can not understand why this can not be covered by the sheet?
Would it be the front-facing camera, I could understand it yet ...
The Protector is offered as exceptionally scratch resistant, unfortunately I can not confirm that.
I have a cell phone used normal, so do not make an extra with an object attempts a scratch, although several small scratches were after a few days already on the back sheet, the demand side seems to be a little more stable, and there are now small scratches, but substantially less than at the rear.
All in all I think the cheaper films almost offer the same protection.
