I have put on unknown amount of screen protectors on cell phones and tablets. The process started off fine but the first gotcha was with the dust remover. Way too sticky. I had a hell of a time trying to get it off the glass every time. The next issue is that even though I got though the dust removal, was installing the glass. This is normally not a problem, remove the protective film and gently set it on the screen. Modern glass will just go from edge to edge with little or no bubbles. This started great, but there was 2 small bubbles that had to go. No matter how much I tried, no joy. Long story short. It fail, and unless I wanted to stare though the bubbles, I have to remove and throw it away. Which is what I did. Normal packages come with 2 if not 3 glasses, but this didn't and I am basically screwed.
