This screen protector does an excellent job of protecting your phone from scratches, but it requires a lot of patience (and a very clean room) to apply. If you get any lint, dust or oil between the screen and this protector, it will be very noticeable when you use the phone later. Of course, since the screen protector is coated with adhesive, it's practically a magnet for dust. But since this is easily washable, it can be applied cleanly with the included squeegee and an appropriate amount of care. Once you have the screen protector on, it won't come off unless you want it to, but when removed, there is no residue left on the screen. All in all, a good product as long as you don't mind taking the time to apply it carefully and in a dust-free environment.
