Mine came in today. I bought this one:
Premium Tempered Glass Screen Protector film for Nokia Lumia 1520
Pros:
+Feels just like the screen itself
+Amazing sensitivity and clarity through such relatively "thick" (protective) glass
+Easy installation
+My seller shipped mine in only 5 days when the estimated delivery time was 10-14 days
+Install kit has simple instructions and comes with everything you need
+Size is perfect. No overhang or anything.
Cons:
-A tiny portion of the edges of the protector does not actually stick or adhere to the phone itself. I don't know if this is because the edges are rounded on the 1520 or because there is no adhesive material on the edges of it, but it is uniform around the whole protector where it is not stuck down like the rest of it. This could be by design or because of the 1520's screen shape. Either way, it is very minor, and has not caused any issues. I don't really expect it to, either. It's more of just a small visual thing like you have a white border around your protector but it's not a big deal at all for me. It looks just like the person who posted above in terms of not sticking down on the sides but I centered it perfectly and it's completely fine for me.
Summary: Highly recommend it. Best screen protector I've ever used. Much higher quality than ZAGG Glass.
