So I blew $30 for an Anti-Glare one from Japan
The official ones didn't really hit the mark to be honest. I could feel their adhesive getting noticeably weaker the very second time I tried repositioning them.
Get yourselves a PET film one, way easier to apply, less prone getting damaged by bending and it's thin as paper so it actually closes. I'd reccommend PDA工房.
So yeah, on a side note:
-Wait for the bathroom to be VISUALLY steamy, not just humid. If you have a mirror wait for it to get completely foggy.
-Leave the goddamn dust infested bath robe out.
-Wipe the screen GENTLY and let it rest between tries, wiping builds static that attracts dust
-Let it rest for at least a day before trying the grip on, and be careful it doesn't catch on the edge when you do
And lastly, expect your first try to not go smoothly...
Also, does anybody know if silicone adhesives are "washable"... ? As I heard.
