I have been using tablets and smartphones for many years and have had many screen protectors for these devices. Because I like to suffer, I have often mounted these protectors myself with the resulting dust, blisters and crooked settings. That is different. The instructions are very good. There's even a video. The time frame for tread alignment greatly simplifies installation. I got bubbles at first and managed to push some of them to the edge of the screen and use a screen rag to remove them. but I've found that for the stubborn, if I just lift the edge of the screen protector a bit with my fingernail until the air space underneath the screen protector connects with the bubble, and then let it fall on its own, it will repair itself. I am delighted with my protective screen. Another tip: If possible, attach the screen protector in a dust-free and damp environment. The sensitivity is excellent. It's not visible on my tablet and I know the screen is less vulnerable.
