I've been using since time immemorial only matt, anti-reflective films. Of course, it comes to the so-called. Moiré effect, which means that the representation and "brilliance" of the screen suffers a bit and you, if you want it because, especially in white backgrounds often small "play of color" looks.
However, I guess the matting effect, minimizes fingerprints and readability in bright (sun) light significantly increased (the summer is approaching).
The fit is very good. The films can be bubbles attach.
Am now practiced and not shy in front of the attachment of large-area films.
Tip: If dust between the film and the display has: Never throw away or otherwise annoy. Just let the foil rest (if it is reasonable for), lift with a Tesa strips to one of the four corners and dab with test film from the bottom between the display and slide the dust grains and mini threads. Works 100%. Have no dust inclusions themselves on the big screen of the iPad.
However, this procedure is recommended only for patient contemporaries. It therefore before half an hour until we could achieve a perfect result. But it's worth it :).
