my only problem with the spigen protectors is i have a hard time getting ahold of the little tab to peel back the protective sheet. last year and again this year i wasted the first one by disarranging the actual glass struggling to peel off the cover. success on number 2. once it’s on, my 14pm lasted all year looking and feeling good. i just buy 2 boxes. i honestly prefer the amfilm protectors because they ship with a full screen sized dust sticker. really easy to get a dust free install. i place the dust sticker over the screen, rub down and then don’t remove until i have peeled back the sheet on protector. but i don’t think they last as long as spigen’s. when they go on sale i actually buy 1 or 2 for the dust sticker. i tried to find full screen sized dust stickers on their own but couldn’t.
