For me, the button install wasn't as easy as it looks. I had already installed a GlastR when I decided to add a button. Getting the button set exactly centered & square over the home button was no easy feat with the Glas already there. If I had to pull it back off to re-center it, it was harder with the thickness and close tolerance of the glass in the way around the home button. So when I started over and replaced my GlastR with a pure, I set aluminum button first then set glass afterward and that was still a bit challenging on the button but easier to do it first then afterwards.
