Great protection and easy to install
Having had gorilla glass before and being a pain to use with the fingerprint or alignments, these are really good. Comes with everything you need and makes the phone feel like the same screen. Fingerprint works when you adjust the settings and so easy to fit with the alignment tool. Definitely buy again

Excellent in every way!
I have the galaxy s21 ultra. I cannot tell you over several phones how many screen protectors I have purchased. None have been great. They feel like rubber, after a few days they get a bloom over the surface and none have allowed me to use biometrics successfully. I was so sick of this and the last one I bought became very difficult to do anything and looked misty. I couldn't clean it. In desperation I searched all reviews and details on here for days. I came across this one and something made me order it. What a complete turnaround was this amazing screen protector. It was simplicity in itself to apply, covering the curve just enough without causing any problems with my back case protector. I can remove that without problems. There were a couple of tiny pin head bubbles on the bottom right corner that I couldn't smooth but really small. It was gleaming like the original glass screen. I left it overnight and the next morning the bubbles had disappeared! Apart from the camera cutout top centre I would argue there was no protector on my phone, as it looks and feels exactly like the original screen. To say I'm amazed is an understatement! The biometrics works first time every time and my finger slides across the screen with ease. I left it for a few weeks before writing this review and showing a photo in case it got the bloom all the others had. You can see it's like clear glass and I can honestly say I have not had to clean it at all. I use hand cream throughout the day and there has been no fingerprints on the screen whatsoever. I highly recommend it. You get three in the box with instructions and everything needed for a speedy successful fit. Watching the video would be helpful. If you decide to try this you won't regret it, I'm still elated after years of being fed up with others.

Crystal Clear / Easy Install
Quite often the install videos make it look easier than it is in reality to install, not this one, it really was quick, simple and super easy to get this onto the phone completely blemish free, shocker!! Only installed yesterday after a speedy delivery, so can't talk about durability, but I can say it feels nice, the finger print scanner works perfectly, unlike what it replaced, and the screen is crystal clear with it on. Not a fan of the glass protectors they always crack, but likely give an added level of protection, I don't drop the phone often so hopefully when I do it will hold up with this on. Would recommend from early analysis!

Great replacement for OEM
After four years the protector from Samsung out of the factory was starting to peel and was scratched. This is a fantastic replacement. The screen cleaning kits with dust removal was great and worked well, application was generally easy after watching the video. Had two attempts as the anchor points aren't great and first one was mis-aligned with the front camera. Stick to the screen well, no air bubble on the main area, just a couple on the screen edge probably due to the nature of the phone. Fingerprint recognition worked straight away. Not as thick as the Samsung one but will see how it goes. Overall very impressed and Crystal clear.

Easy to install and decent quality finish
Great triple pack which is a good idea as, adls good as I gave the first screen protector install, there was still a tiny dust particle and faint crease mark on the screen protector. I had to do it again and this time was much better results. My fingers glided and touched the screen like there was no protector on it. The screen was as responsive as without the protector. Fingerprint works fine. Very happy with the easy to do system. Preparation is key.

very bad product
The listing claimed it was easy to install, beginner-friendly, dust-free, and bubble-free. Sadly, none of this was true. I followed the instructions exactly as shown, using the guide tool and roller system properly, yet both protectors ended up completely ruined.

Amazing 😍
I don't understand those people who say that the fingerprint doesn't work or works badly. Yes, there is a slight delay, but the fingerprint works perfectly, after adding new fingerprint. Overall, this ceramic screen protector is amazing and very easy to apply. I would definitely buy it again.

Didn't work the first time. Was it me? Definitely did this correctly following the video
I'm not sure if I've got a faulty one but the first screen protector that I tried to fit did not stick at all. I've watched the video several times before doing it but there's no tackiness to the protector, just the green strips. I even checked that I didn't put it on the wrong side up but both sides are dry. Not going to give one star until I've tried with another but am asking for any suggestions in case I'm still doing it wrong
