I followed the instructions to the letter and I could apply the screen guard on my tablet without problem. Just be patient, to take the necessary precautions (damp room, personally, perfectly cleaned screen to get it out any bubbles with the squeegee), and the application runs right the first time without any bubbles or trapped dust.
The film itself is pleasant to the touch, it does not alter too much contact with the screen, the slip is correct. He lets go perfectly the colors, I did not notice any significant loss of brightness or annoying reflections.
