It's a shame that this great idea doesn't deliver. Love the ease of alignment and positive lock on the device but you just can't get a good outcome from this design. I've done three of these now and even with years of experience applying this and other screen protectors it is very difficult to get the bubbles out. Another issue is the curved edge which just will not stay down long enough to seal without eventually getting lint under the edge. In addition, pressing down to remove the initial bubbles causes a corner to come up and need a rework the area. Giving up and moving to case with built in cover.
