3 Pack Ultra Glass Screen Protector for Galaxy S21 Ultra Tempered Glass Shield Full 3D Curved Edge 100% Ultrasonic Fingerprint Unlocking Easy Install Kit for Samsung S21 Ultra 6.8 inch

very good quality and an excellent price

Ok I cracked my screen just barely, but it had one like pit that you cold feel and hairline cracks to 3 corners of the screen. I tried a cheap glass screen protector that did not have the glue and it sucked, yes it covered up the cracks so you could not feel them but because of the tiny air gap the screen showed reflections like crazy and was not as bright as before. Worse yet it had like a sticker where the fingerprint reader was so you could obviously tell the difference where that sticker was compared to the rest of the screen that did not have the sticker.This kit worked SOOO well, yes it's tedious to install, but now I can't even see that pit from the crack and only if I get the angle just right can I see that the screen is cracked at all. Because the glue bonds the cover to the screen you don't have the problem with reflections (no air gap between them) and the screen is just as bright as before. Just make sure you use the "level" app on your phone to make sure your phone is absolutely level (really, not just close, but as perfectly level as you can get it) before you put glue on screen. I ended up putting tape under the one edge of the holder to get it perfectly level. I wish I had before and after pics

I have bought so many high scale tempered glass screen protectors it's ridiculous. This is the ONLY one that held my phone hostage and made me fear the potential of it breaking while trying to free it. This says it's for an ultra. With the foam side protectors in the clear device I COULD NOT retrieve my device. Also, I place my phone FLAT on FOUR different surfaces, and according to my phone, my home or all four surfaces are at a slant, because the liquid would not stay in place. Quite frankly, I'm irritated in the total amount of money I've wasted on screen protectors that in theory seem like they would do a good job, just to be bamboozled. Also, the fumes from the liquid has given me a headache.

Once you get a bubble you are done for. Glue goes everywhere. Bubbles won't go away. All you can do is cure it and try again. They unfortunately need to put a better system of installation together. Am sure it is great once it goes on perfect but this will be returned if can't get bubbles out by the third try. Not my first screen protector. But I think the old ways work better. They should use adhesive. This UV just causes a mess. Glue blobs all over the top of it now. Won't someone make a good temper glass protector for s21 ultra? Second one and not impressed. Actually it does not fit to edges top and bottom either. I like the $6 days. Never had issues in the past.UPDATE 12/15/21: I tried it a second time and it went smoother on the install. but the same thing happened. I got a small bubble in the middle again. No idea from where. I had to push it out this time rather than peel back the cover. I managed to get to work and somehow get the bubbles out.I do admit it is a nice screen and does not get fingerprints as bad nor reflection. So Kudos to that once it is installed it is good. but if you have to take it apart for a bubble good luck. Just try to push the bubbles out if you can.

I was a bit nervous about 1) Putting it on and getting it straight, 2) Would the finger print reader really work once the screen saver was applied, 3) Could I get it done without any bubbles.I am EXTREMELY PLEASED with the end result !!! Phone looks flawless and the screen protector works with both of my cases. Fingerprint Scanner works just fine (I did have to re-register my fingerprint once the screensaver was applied). Installation was much easier than I anticipated!!!My suggestions if you are considering this product:1) Watch the installation video a couple of times before you start. Make sure you have the steps down.2) Make sure you have a clean workspace and take your time.3) Make sure your work surface is level. I wanted to make sure the glue would spread / flow evenly, so I leveled the desk before starting. Check your work surface and use a shim if needed to make it level.4) Like another reviewer suggested, I did stack 4 Quarters on top of the weight before activating the UV light. I also let the first curing go 90 seconds. Then on the 2nd curing I went with the manufacturers suggestion of 120 seconds.5) Clean off any excess glue ASAP with an alcohol wipe and scraping if needed with your fingernail.Again, very happy with the results and would highly recommend this product if you want a tempered glass screen protector and still be able to use your fingerprint scanner.
