Here we go! Finally got around to adding it on. I used the ICarez matte and the AmFilm tempered glass. My case is the Moko Rugged.
Photos: there's a few bubbles of dust stuck in there, but I'm WAY too lazy to remove them at this point. I'll do it if they bother me later.
Apple Pencil: working perfectly
Case: slightly finicky, but if installed properly, it will be okay :)
Notes: I had to cut the edge because I installed it too far on one side. I picked it up and re-did it once, but it was still too far. It had been two hours (on and off) and I didn't care anymore, so I trimmed it. When I pick up and jostle the iPad, it does fine unless I pull the edges; then it would push up the screen protector. I can just push it back down though; all's well that ends well.
My bad! I should have included it.
