The product came in a speedy manner, 3 protectors in total. So far I only used one. I know a lot of people complained that they got a lot of bubbles when they applied the screen protector, but I believe they just don't know how to put on screen protectors properly (no offense). I was able to get the product on my phone with 0 bubbles. Most people don't know but the key to this is regular tape and a microfiber cloth.
First wipe down the phone with the cloth, don't use napkins or paper towels because they always leave something behind. Event the microfiber cloth dosen't clean it 100%. After you think its clean, take a piece of tape and dab it all over the front of the screen, because there is debris that you can't see with your eyes which is what causes the bubbles. This should reduce the bubbles by 90-95% Now when you put the film use something flat like a credit card to slowly smooth the film down from the top -> bottom. As you do this you will notice a few bubbles on the way, don't panic! just slowly lift the film back up a bit, take another piece of tape and go over that spot on your phone AND the underside of the screen protector. Sometimes some particles stick to the film itself. The tape is stickier than the film, and should pick up the debris. Dont' be afraid to lift the screen back up. Then just continue smoothing it down with the card till you're finished.
If you happen to accidenlty let go of the film and it goes down, just take a piece of tape and touch it to a corner and that should lift it back up. Also lifting the screen protector up and down won't make it lose its stickniess since the glass is clean. These are just helpful tips and tricks I've learned from applying screen protectors on multiple phones for my family members and friends over the years. Hope this helps!
On a side note, I noticed that this screen protector is a bit more cloudy than my last one, which is why I only gave it 4 stars.
