got the amfilm on my xl 2 and it's pretty nice
Fit great, easy install for me and, with a typical case on, the look is perfect. Not sure if mine was from a 'bad batch' or not, but I have had one problem with it (and no, it hasn't been it falling off - that hasn't even hinted at being a problem over the last 4 days with which I've been using an MNML case (same as peel) that provides no shelter to the edges.
The problem I have is that, despite never having dropped it, bumped it, kept it in my pocket with keys or anything else, nor being hamfisted when using the screen, it has developed two hairline cracks in the SP. The first appeared just below the upper left corner after about a week, and the second a day later (not at all connected to the other crack) on the lower right side, about 1/3 up from the bottom.
I'm hoping that it's just mine, but am concerned that it may have to do with accrued stress since the SP actually floats just above the actual display, only fully seated on the edges.
