I started off with the ESR tempered glass screen protector, but due to recommendations on this form I upgraded a few days later to the ESR Armorite screen protector. I have had the Armorite on my iPhone 13 Pro Max since Sept 29th and so far there is not a scratch on it.
This is my first time using a screen protector and I’ve had an iPhone every year since the first one in 2007. I’m really happy with it, even when I hold the phone under a light I really can’t see any scratches.
I watched some reviews on YouTube and there are a range of screen protectors rated higher than the ESR Armorite, but so far for me it has been great. I’m also glad it came with two in the box, as I didn’t do a great job of applying the first one and it had to come off right away.
