Ordered for my Z3 this bulletproof glass / foil. Have already been tried and changed several times different film. NO AND NO really is as good as this one. First super shipping, good "tool" here to install. (Clean cloth, microfiber cloth, special strips to remove lint) Guide was easy to understand, packing top. Leave after cleaning, align glass, fall on your mobile phone and press once with your finger in the middle of it. No bubbles! Super feeling to the touch!
