The product was delivered quickly and in perfect condition. Since the iPhone was also brand new, I've dispensed with the supplied cleaning wet / dry cleaning cloths and the display glass cleaned with a dry cleaning cloth for glasses. The protective glass could be put on easily with the accompanying description. Due to the stability of the protective glass, the orientation is on the screen very easy considering protectors. After hanging up the accounted "smoothing" to remove small bubbles, the protective glass sucked firmly independent and completely free of bubbles. After installation of the glass, there are no restrictions on the operation of the touch screen, the iPhone responds just as sensitive to touch as before. The protective glass seat safe and stable on the screen, the openings fit perfectly. I use the iPhone with a Spigen Tough Armor Cases and gives no restrictions (eg, touching or difficulty in removing from the case) in this combination! I can not comment on scratch resistance and durability of the glass over a longer period. Although the glass was not purchased directly through Amazon has all the formalities and the payment handled smoothly Amazon. I am completely satisfied and can only fully recommend this protective glass at this price!
