GREAT
Really pleased with these screen savers, paid £5 for 3 which is absolute bargain!The first one I applied seemed to have a little trouble bonding at the Lower right corner of my phone so removed and applied another screen protector which was fine. The fit of these screen protectors is fantastic, they fit perfectly around the screen area and the alignment tray that is supplied makes this process extremely simple as the try snaps nice and tight around the phone frame. The install went perfectly, not one air bubble! Just start at the top of your screen and lay the protector down and you’ll immediately see the protector sucking on and bonding to the screen! Remove the alignment tray and work around the edges with a lint free cloth or wipe which is supplied just to ensure that it’s bonded properly and then your done! The whole process takes around 10 minutes if you want to be really thorough, the trickiest part is cleaning your screen off and making sure that dust doesn’t settle back down on the screen before applying the protector! The clarity of the protector is fantastic! Can’t even tell you have one on the phone! For people saying that these are not glass! The one used 1st that failed to bond I bent in half and after nearly doubling it over it shattered! the glass stayed in one piece due to a protective film. If this screen protector only lasts me a couple of months I’ll be very happy as I’ll just apply another! Hell you could by 12 of these for £20 pound and put a fresh one on every month if needed! Better than spending £40 on a belkin ultra curve from Apple like i did a couple of months ago.!

It's really good - and I'm not even an AI
I really hope this review doesn't get lost amongst all the rest of the reviews that are clearly written by, or with the help of, AI - because genuinely this is a really great product and I'd buy it again any time!I was switching from the old Samsung screen protector. This one was really easy to apply - stick the plastic guide in the USB-C port, hook the film over the posts, make sure your screen is clear of dust, and then apply one half then the other. There was a handy green sticky strip on the leading edge of the film backing that seemed to help scrape off any errant bits of dust that landed after cleaning. Do that twice, unhook off the plastic, then smooth down the edges around the curves. I genuinely have a completely bubble-free screen protector experience - and apart from the U-shaped cutout around the front camera, you wouldn't know it's there.I didn't reset my fingerprint, found it did read it but had to think about it for a moment, so I have now reset my fingerprint just in case. Fingerprint sensor seems to work a dream now.Already (accidentally) tested the self-healing aspect as I have a bit of sharp fingernail - made a scratch, within 10 seconds it was gone. I haven't gone back in with a diamond drill bit, mainly because I'm not an idiot, but also because I don't need to do that. This isn't going to protect you from that, but it'll protect the phone screen from my keys or something.Literally got it today so can't comment on durability. Phone screen looks as clear as ever - wouldn't say it's particularly anti-glare or extra-glare-y but then again this protector doesn't make any claims that way. Feels silky and is genuinely non-smudgy with my finger grease.Buy it! I won't be for a little while because I've got the other two in the pack, but you should!

Good protection, easy installation
These screen protectors seem decent overall and were very easy to apply. The only issue I had was compatibility with my Mous case, once the case was on, it caused the edges of the screen protector to peel up.

Don't listen to some bad reviews.
Update: 3 years later and I still buy these. 3 protectors have lasted me 3 years. they have only cracked when I've dropped them on a very hard edged surface and have never gone through to my actual phone. Still recommend in 2021!I don't understand some of these super negative reviews. To clarify a few things:1. The screen protector goes over the screen, but not the bezel. It literally shows that in the photos. Anyone who is rating it 1 star because of not looking at the photos and information correctly is at fault themselves. I have no issue with it as I actually like it that way as it means I can put different kinds of cases on the phone without the protector getting in the way and it doesn't scratch my fingers on the side of the phone :) The bezel also kind of curves at the edges of the phone, so putting the screen protector only half over the bezel would surely look awful?2. I have never applied a screen protector myself and found this easy as hell. They give you more than enough things to get rid of dust and applying the protector itself was easy with the plastic aligner thing they give you (no idea what it's called lmao) so I don't see how people can struggle unless they didn't watch the video they said to watch beforehand.and 3. I had a few little bubbles myself but they disappeared after rubbing them a few times.Just wanted to get those few things out of the way as I kept seeing people complain about those 3 things in particular! I've found the protector fine so far! My only negative about them is that if you usually have quite sweaty/moist hands like I do, you can easily leave little finger marks on it. Think that would happen with any screen protector though to be honest. They feel good quality, but I haven't dropped my phone yet so I can't fully say if they're good at protecting from drops!

Perfect fit. Perfect clarity. No bubbles. Easy to fit with mounting tool
Second time I've bought these. Absolutely flawless. The charge port mounting clip keeps it perfectly aligned, following the instruction video (provided via scannable QR code) and using the wipes and dust removal stickers prior to applying the film works a treat. No bubbles, no dust. and perfectly fits around the curves of the phone without issues (I found the hard glass type covers to never grip the curve) Also these don't crack like the glass type screen protectors, and are way more transparent. 100% recommended. My previous pack of 3 lasted about 2.5 years. I just changed them if I thought they looked a little tired since they are so cheap.I have dropped my phone many many times and not had a cracked screen for years.

Great screwn projector
Great screen protector. Goes on very easily and great instructions.

Some install issues, but a good protectors once on.
Once they're in they're really good protectors, no issues with finger prints or stylus etc, and the installation is easy to follow. However, I had to use up two of the three because the projector wouldn't separate from the film so that wasn't ideal when I had two phones to do. They fit the phones well though so I would say they are good, just be aware that some of them may not be a smooth install, but once on there great.

Super Folie mit Spigen Hülle
1A Folie für Samsung galaxy s23 ultra, schmiegt sich auch den abgerundeten kanten an, instalation ist auch sehr einfach und praktisch, super alternative, da panzerglas mittlerweile nicht hält oder schwer zu bekommen sind mit UV kleber. Ich habe die Folie mit einer spigen Hülle passt super und drückt auch nichts hoch. Kann ich nur empfehlen.

Buena calidad
Lo he recibido hace un rato, la verdad es que encaja perfectamente en mi Samsung Galaxy S21 5G, el material parece de muy buena calidad y resistente, y el diseño peinado de la parte trasera me gusta mucho, solamente le añadiría algo de goma a la parte trasera para mejor adherencia en superficies planas.

Super protection
> Super protection, je prends toujours cette marque LK et ils se sont encore améliorés. Ils ont ajouté un embout pour faciliter la pose, c’est vraiment le top. En suivant la vidéo d’installation, aucune bulle sur le téléphone et la mise en place est très facile. En général, elle dure dans le temps. En plus, il y en a 3 dans la boîte. Je recommande à 100 % !

Super produit.
Acheté en dépannage, finalement ma femme en est super contente. La protection tient bien dans le temps.Top! En plus le kit d'installation fait que c'est super simple même si nous ne sommes pas des pros dans l'installation de films de protection.

Prodotto di ottima qualità, installazione semplicissima e confezione ben curata.
Finalmente la prima pellicola che non richiede una laurea in ingegneria per l'installazione, permettendomi di non buttare soldi come spesso mi capita in un acquisto su tre, a causa di installazioni venute male.Nella confezione ci sono tre pellicole in vetro, tre coppie di salviettine bagnate ed asciutte, 3 stickers per la rimozione dei pelucchi, un pannetto per la pulizia delle superfici in vetro (verosimilmente a quello degli occhiali) una guida di installazione ed un coupon che dovrebbe farvi ricevere addirittura un caricatore wireless gratuito.La semplicità di installazione grazie alla guida inclusa mi ha piacevolmente stupito, se solo penso a quante ne ho buttate negli anni anche solo per averle applicate storte. Con un po' di pazienza riuscirete ad applicarla nella maniera piu dritta possibile in pochissimi istanti, ve la consiglio assolutamente!Bolle d'aria non se ne sono formate per niente, pelucchi neanche, pertanto applicazione riuscita al primo colpo.Adesso devo solo vedere quanto durerà, ma vi terrò aggiornati.Non credo ci sia altro da aggiungere, pertanto se ti sono stato utile fammelo sapere cliccando sul tasto qui in basso. Grazie mille!!
