I bought this for my protection compact Xperia Z1. Protection is really a perfect size and a great finish.
The big downside was the second day I drop my mobile phone on the floor, on a flat surface (floor ...) and it glides over 10-15 cm. Result: The protection is damaged on all sides. In short it is surely an extreme case. Because honestly this glass is here to protect from scratches and small pointy nails style or stone impacts.
Ps: To place, I advise you to do it in a damp bathroom (personally I'm turned the shower for 3-4 minutes at the highest temperature), so that the dust particles fall to the ground. Do not be afraid because in any case, the Xperia Z1 Compact is waterproof!
