The screen protector fits my iPhone SE2nd generation well. It was easy to install and has a smooth surface. I am pleased that there are extra screens provided.Please note that this is my second purchase of Ailun screen protectors, the first one being a couple of years ago. Each time I replaced the protector, it was easy to replace, with a minimum of air bubbles.Of note, a few weeks ago, I accidentally (again) dropped my iPhone. And while I drop it fairly, this time the fall was substantial. As a result, there was a deep chip on the screen, and shattering of the screen in several places. I thought for sure the phone itself was seriously damaged.Upon removing the screen, the phone screen was in pristine condition, no damage whatsoever. In my view it works well. I would happily purchase again.(Please note I have a phone case protector as well).
