AilunScreen Protector for Galaxy A21 3 Pack Tempered Glass Ultra Clear Anti-Scratch Case Friendly

without being too negative, because they are very nice, what we got seemed to have been bent slightly before we even got them because there were bubbles under the corners that simply would not go away. i've put on hundreds of glass screen protectors for my husband and my phones over the years, so it was definitely not user error in this case. occasionally things will have defects but it was probably just a one-off since it was the first protector in the pack.all in all its a good buy in my opinion!

I bought these back in January and thought they'd be good to last me a little more than just a few months. After my phone slid out of my pocket on Mothers Day it had a few hairline cracks on it which was a little unexpected so I placed my last one on that night. Not even two weeks later I set something on my bed where my phone was to find more hairline cracks at the bottom of the protector. It did a great job protecting my screen but I thought these may have lasted a little longer than they did. If you're looking for a long lasting screen protector I wouldn't recommend these protectors as they only lasted me a few months (though I don't know how long one should last.)

Love it. It doesn't have a cut out for the camera but the front camera still works fine. Easy to apply.

In a nutshell, it's a good product except for the fact it doesn't cover my entire screen. However, I have dropped my phone on a few occasions and luckily the screen cover DID protect it. It is very durable and easy to put on. Next time I need a screen protector, I will most likely look somewhere else to buy one since I want it to cover my entire screen.

I actually bought these for my mother who has the a21. But I could not find any good protectors for my s20plus. They all only had adhesive around the very edge and after a day or two popped off or slid around on my screen. I remembered applying my mothers protector and how this protector had full side to side top to bottom adhesive! I checked the screen size and they're the same, 6.7 inch. If this protector was 1mm bigger it wouldn't fit. However it fit perfectly and super snug against my case! I just have a basic clear case with raised lips and it fit mine perfectly. It even put it over the factory protector from Samsung. Double protection, no sensitivity loss when tapping icons. So happy. Thank you! My mother aunt and I all love these protectors.

These are lovely to work with. When I set them on the screen they adhered all by themselves. I didn't need to use a card or other straight edge to push it down and push out bubbles. The trick is to make sure there's not one speck of dust and you line it up correctly. These include the stickers to help with placement and the stickers to pick up dust. These fit my A21 phone perfectly and they protect my phone screen very well.

The protector works as intended, but do take note that it is a little small, not easy to install as they claim. The packaging could be better. Also, it should include paper instructions, not have the instructions on the box itself.I have had the protector on for at least 7 hours (at the time of the review), and there are still bubbles present.The phone still works as intended, so as long as the bubbles don't cause issues, I am not really worrying as much.

Pros:- Durable and clear- Fairly thorough instructions for application- Extra screens and wipes etc (you will need them)Cons:Supposed to come with a guide tool that clips to the phone to help align the protector, mine DID NOT come with any such device and consequently I went through two of the four shields before I painstakingly got the third to line up with no bubbles. So do not expect an applicator guide tool, and do expect some stressful hand-eye cordination.
