Apple iPhone 5/5s ScreenGuardz Pure® Premium Glass Screen Protector
Product Review (submitted on June 6, 2013):
LOVE, LOVE, LOVE the Pure Premium. it is smooth, clear, doesn't scratch like others, and easy to install without pesky bubbles.
CON: despite being very easy to install without any bubbles, I did have two show up after the screen protector had been on for a couple months. not sure why, it is positioned well. But they are on the side so not a huge deal.
