Write Great lot not necessary to do so, I would just say, they serve their purpose.
The thickness (thickness) of the film seems to be quite adequate and the fit is very good.
Dexterity required, so you should definitely times 15 minutes for it to take time before you have to be angry afterwards ... - For the application - also as with all other protective films
"Crystal Clear" I can recommend, is applied on mobile phones hardly visible!
EDIT: And here's my "but":
Good 3 1/2 weeks was all wonderful, but now I have to say that the film has a weak point!
The upper right corner, here is a recess for the sensor of the Xperia Ray and that's where the film goes off!
In the long run so not the best solution! Too bad ...
