One can not so careful with a cell phone or camera, sometime you have but the first scratch on the diplay. A protection is therefore indispensable, where according to my requirements, this may have no effect on brightness, contrast, brightness, sharpness and sensitivity of the touch panel. My best experience I have generally made with hardened glass and therefore this time the iProtect Screen Protector ordered. As with Amazon usual, the glass was delivered within the shortest possible time. Supplied were a dry and a wet cleansing tissues next to the glass as well as a "dust-absorber" to it, however, in the description was no information and I could not recognize the benefits. The "fitting" of the glass with residual protective film showed that the fit is very good, only the camera opening is minimal but without compromising off-center the camera function. Then dust off everything tidy with the included cloth to clean the screen (the cleaning effect was excellent), remove the protective film on the glass and carefully fit. The exact center hinzukriegen is not easy and you should practice it before removing the protective film. The glass sucks then literally on display determine what can be observed well. In the end I had then but a bubble, but could be relatively easy rausdrücken sideways. The result on my optical expectations I am 100% conditioned satisfied. How scratch-resistant is it really, only time will tell. After about 1 week, at least not the slightest scratch recognizable. It is only I noticed that the surface easily soiled or finger marks are more visible than in the original display surface. Perhaps there is a corresponding surface coating was used, the other hand, can also scratch. Then rather without and therefore there is also no deduction. Finally, may I say only an unconditional buy recommendation.
