I have used and installed several other glass screen protectors on other phones including those that came with a 'setup tray' like this one. With some other screen protectors, the tray didn't fit the phone properly, or the screen protector didn't apply easily (it got stuck and jammed when trying to push it into the tray). Others had the tray self-aligned, but it was completely unclear how the alignment should be. When installing with this protector, there were no such problems. "TOP" was clearly printed on the tray/basket. Spring. TOP, so it was incredibly clear how to place it on the phone. And when I decided to drop the glass into the tray, it sat at just the right height - so I could place it just right without feeling like I was about to break the safety glass. Touchscreen usage/screen clarity/etc. is "average" - meaning they are all pretty excellent, and this one is excellent, as are others I've tried over the years.
