My opinion about the privacy filter is shown there.
To me it’s not very effective, only from the upper left or the lower right angles, not at all from the other diagonals and in-between the two, mediocre.
EDIT:
@BierTroll, could you precise from which point of view (right/left/upper/lower/diagonals) and at which angle (in degrees from being right in front of the screen) your screen is well hidden or not? I’m curious to see if they’ve changed it.
It feels very smooth and slippery.
