ZAGG - InvisibleShield® GlassFusion VisionGuard+ with D3O Blue Light Filtering Screen Protector for Samsung Galaxy S21 Ultra 5G

I almost wanted to give this Screen protector a 5 star. Then i almost gave it 4 stars. I settled for 3 stars because 1. The screen protector didnt grab the sides of my Galaxy 21 ultra. 2. Punctured after a fall on Day 2. I gave it a start for the easy application (Although i had the store associate do i) I also gave it a star for having some kind of warranty (Which is why you pay so much for it in the first place) The third star because it does what it was advertised to do. They supposedly self heal and they do with small rubs. You can only expect the resistance to punctures and scrapes to be so much before youll need a new one. Now the adhesion. I took a star away for that because right after i had the georgous young lady mount the protector to my screen, i went home and took out my heat gun just to warm up my screen and applied pressure for around 20mins with my screen being warm to help it stick. I left my phone laying on its back to promote gravity keeping the pressure of the protector against the phone's screen. Being i kept my old phone, it worked as normal so it was easy to leave my 21 Ultra alone while the screen protector works its way to sticking to the screen. Day 2 is where all the schenanigans came about. Phone fell and something punctured the screen protector (Phone's actual screen is fine) and the screen decided it didnt want to stick to the edge on the left side of the screen. The good part is my actual screen is ok and although there is a warranty, i will go and find out the procedure of getting this protector changed out,

Overall, I have always like Zagg shields. From a person who has, in the past, dropped their phone a lot (and I do mean A LOT!), I can definitely tell the difference from having one and not. Thankfully I have not dropped this phone yet (Knock on wood), so I cannot speak on this shield's protection. However, I can say that it does not seem to hinder usage of the phone. I do not like the fact that the screen is not long enough to cover the entire screen but I do not believe this would hurt the protection capability; especially with the phone being in a case.

My husband is rough on his phone. This item has protected his phone very well. We had no problem getting a free replacement when it got scratched. It really helps our eyes with the blue screen. Not cheap, but worth it!

Pretty good quality screen protector. I feel like I'm able to view my screen longer than usual because of the less harmful blue light.

It does not stay well on the screen of my S21 Ultra. The sides are lifting. The product actually already chipped and I never dropped the phone. It also shows impressions if you use your finger nail on the screen or something with a dull to sharp edge touches it.
