I've had iPods, smartphones, you name it. This was by far the worst screen protector I've ever encountered. It was a complete waste of money. I am thoroughly disappointed and wish I could get my money back. No matter how hard I tried, I could not work out the air bubbles. Placing a screen protector is not new to me!
