This display cover can be in contrast to various smartphone Protectors easily attach (you just have to make sure that they are applying exactly parallel to the edge of the display), and a correction is by detaching and re-laying easily possible. The fact that the film adheres only to the edges (liability is nevertheless perfectly) the active LCD surface is affected in any way. The visibility is excellent, no loss compared to the unprotected display.
Premium Sony quality, which can discourage the use of uncertain Second Manufacturer brands. About longer term use experiences of course I can not say anything for the time being - until now but clear recommendation!
