The protective glass was delivered in aktzeptablem period. The aufbringden the protective glass was a bit fiddly - went at the end of yet. The protective glass could in my opinion be 2 tenths shorter, which would facilitate positioning on the Jaiyu 4Gs something. The protective glass is very permeable, does not lessen the sensitivity of the touch screen and can be cleaned easily. Therefore I am so very happy. Had previously a film that was but zerrkratzt quite fast and has little tarnished the great resolution of the display. I would buy it again - but the hope is not necessary as quickly. Great Product
