While the installation guide could be further improved to state clearly where the handphone install guide outline can be placed at (apply directly on top of the phone screen), other than that, the installation of the new screen protector is so easy since the guide outline would eliminate the process of one having to position and reposition the protector if it’s not in the correct alignment with the screen. It is an ingenious method that solves users’ dilemma and improves user experience. If the protector does last after a reasonable time period, I would consider buying from this company again.
