This protection is qualitative and snug for Sony Xperia Z2. The glass is sized to near the top of the screen. Another protection is also provided for the back but is not tempered glass. The hydrophobic and oleophobic properties seem effective. I have the impression that the traces remain less. In all cases, a handle sudden, some traces are erased. For cons, the NTICE is in English and very short, I do not know if I've followed all the instructions: 1- clean the screen with the towels 1 and 2 2- apply the "blue" film to remove any impurities and remove this film with the two tabs (I do not know what is the second) 3- apply the tempered glass.
