Provides good protection, can be very clean and above all easy to attach to the display without much fanfare and frills! The important thing is the display should be thoroughly cleaned 1x, as you know yes by default, so that no small lint or dust particles, dirt, etc. afterwards are lower. I have the protective glass clean and carefully at the screen below created / directed and looked at the fingerprint sensor fits obs and then completely laid on the display, the rest went almost by itself. The protective glass has stapled without air bubbles or the like to the display, am still 1x hand fits over it, sitting does not wobble and has no air =) Must confess have the manual does not really noticed or used was almost as if by itself, if I as at times the "normal protectors" think back and I had in mind how many also compares botched or glued though I had read the instructions .. . think the times are with these Tempered glass / bulletproof glass etc. films past.
Beieinträchtigungen I've noticed no. I write a lot of etc. so I am really pleased with this, should notice what my review is changed, the time will tell.
Also very good as seen fits in my opinion to a Spigen Case, I like the pictures is a red drum and am as I said previously completely satisfied with the combination.
