Pros:
-The package that the Screen Protector came in had a clear shoe print on it, but nothing inside was broken. Everything comes in a sturdy case, which seems to have protected the Protectors from being stepped on.
-Installation was pretty easy. The top of the Screen Protector did stick where it wasn't supposed to at first, so I recommend using both hands to hold the Protector against the installation tray before letting the Protector slide down to the screen.
-There were no bubbles under the Protector. At first I thought it wasn't even touching the screen, but it was! I put the top of the Protector down first, and then tilted it the rest of the way onto the screen, instead of trying to put it down flat.
-The glass feels more like the original screen then film Protectors do.
Cons:
-The edge of the Protector is shorter than the Edge on the Galaxy S9 's original screen, so it gets in the way of Edge swipe.
-The original screen on the S9 is much more enjoyable to use (in terms of the feel of the screen itself).
Notes:
-The top of the installation tray is not labeled, but on the inside of the tray there is a label on the bottom that says "S9 " so put that end on the bottom of the phone.
Summary:
This is a good glass screen protector, that is pretty easy to install. It is responsive, and looks good on the phone. However, the original screen on the phone goes farther around the edge than the Protector, so Edge swiping is a bit weird. It's not impossible though, and I have a feeling that with time, I will get used to it. I would definitely recommend this Screen Protector, and I would have given it 5 stars if it extended farther along the phone's curved edges. However, that small annoyance is a small price to pay for protecting the phone's screen, in my opinion.
