I've only used one so far and it worked well on our new iPad Air 2. Very happy with the product, good value for money. Just make sure the oval cut aligns better over the camera hole. If necessary, have the help of a second person to align before removing the first sheet. Then use a credit card to remove any air bubbles from the screen BEFORE removing the second sheet. Take your time and don't worry about scratches as the second sheet hasn't come off yet. When you're done, you can remove the second sheet. It takes a little patience to remove all the bubbles, especially the small ones. I also tend to move any bubbles closer to the edges or holes of the camera or home button before taking off the second sheet. You will be surprised by the results. If you still see visible bubbles, press with your thumb or finger to remove them after removing the second sheet. I don't agree with the other reviews, I managed to get rid of all the bubbles in the end. If you don't look closely, you can't tell if my iPad has a screen protector. After putting some screen protectors on iPads for the past 2-3 years and breaking them, I think I've learned how to use them well now. I have 2 more in case I need them later.
