Do yourself a favor first. Turn on the shower and fill the bathroom with steam. Wipe the screen. Position the protector in the correct position and use the 3 tabs (there is a great video showing how to use them). Remove the plastic from the back. Take the protector and hold it tight. Place it carefully, but don't press or use the scraper just yet. let them work You can then gently move all the bubbles in and out. I have no dust particles or air pockets. I didn't notice any loss of touch sensitivity on the screen. I don't have a pen so can't comment on that. Some report that they have to press down a little harder with the pen. Otherwise I am very satisfied with the screen protector/anti-glare. I can be in direct sunlight and the screen is very visible. What bothered me the most was that it had fingerprints on it! It was terrible! No longer! I'm a lucky tourist.
