Major shortcoming of this fit and contour precision foil is precisely their fit and contour precision. Although I have no great, uncovered display edges to the sides of the film, however, this has not exactly the dimensions / shape of the screen. In addition, the holes for the microphone and webcam did not fit; at least not when the film was centered on the display. Because of the absence of an alternative product, I even introduced the said holes in the end to the appropriate positions.
The assembly of the film was simple and able to on a single speck of dust properly.
