They do what they want - reflections are virtually no longer exists, the brightness loss I have no problem or I notice almost not.
Unfortunately it is not 100% accurate cut.
I really stuck it just as pointed belongs - above the neckline of the front camera is exactly in the middle - the edges of the left and Rech are exactly vertical, but the section of the Home button is no longer exactly centered. Missing 2mm - does not interfere, but looks visually not quite pure.
Also typical film a bit the sharpness lost, but that these films all so itself.
The surface is a little less smooth - comes my pencils very accommodating - feels much more pleasant than before.
All in all a recommendation - if they would still not 100% fit then if it were perfect.
