Street the bad points of the martin sp seems due to the application. Would you say if it had gone on right first time then you wouldn't have had any problems.
I'm looking to get ascreen protector that's crystal clear and can hardly tell its on there.
I would say my biggest issue was the application, yes. The picture clarity is stunning, very nearly as good as the screen without the protector. The lens protector for the camera is an excellent addition and has brought peace of mind. The 'feel' is also almost as good as the original screen, my finger glides over it easily.
However one other warning, something that doesn't bother me but seems to bother others a lot, is the fact that it picks up grease faster than a bare screen does. A quick wipe usually sorts it out, but it is noticable very quickly.
