Relatively easy to install. Recommend using nitrile or equal gloves to prevent fingerprints. In dry climates, there's not much you can do to prevent static electricity from attracting dust particles. So, try not to be a perfectionist. Otherwise, the installation frame allowed glass to be perfectly aligned with my iPhone screen - which is pretty impressive in itself. Overall, good installation experience (use YouTube videos and arranged a mise en place of all parts to make the installation go a quickly as possible to minimize dust attraction). After installation, I had to spend time rubbing out the air bubbles, but if you keep at it they all can be removed. In normal use, the glass presents an attractive surface on the phones screen.
I've never had a glass screen protector before, so I don't have another glass one to compare it to, but this one was much easier to put on than plastic ones, at least for me, and less likely to get air bubbles in it.
