My coworker was SO thrilled about the new screen protector for his iPhone that he applied to his iPhone this past weekend. (As shown in this online sales demo https://www.youtube.com/watch?v=VGRMq-426m4) He grabbed the hammer out of the tool box to show us. The iPhone was on the desk and he started to hit the iPhone screen with the hammer. WOW it was protecting it! I called my dad on FaceTime to show him how great this screen protector was. The demo started again and then suddenly...the screen on the iPhone shattered.
