This film really fits to the tenth of a millimeter on the display of the Samsung Galaxy S Advance between outer frame, buttons and speakers. This is of course the one hand its strength, on the other hand it makes them excellent fit almost impossible to screen protectors to install so that it does not somewhere a little more than is in front camera, home button or speaker. Maybe it would make more sense, the film about a quarter of a millimeter to make smaller to facilitate handling something. Meticulous cleaning of the surface with window cleaning materials and ideally a dust-free environment are prerequisites for a successful installation anyway the film.
The reflections on the display to remain with the attached sheet remains high (but this is also not explicitly a antireflection film).
Perhaps a disadvantage seems to me as if you would see fingerprints and smudges significantly more with film than with no film.
In summary: product fulfills its purpose, fits, but the application of the film sets the highest concentration and precision expected.
