I spent a good hour applying my screen protector. I cannot accept any dust, bubbles, etc. I think the prep time takes longer that the actual preparation. I turn the shower on full hot and steam up the bathroom. After its good and foggy in there I turn the water off and close the door. The steam seems to take the dust out of the air. After about 15 minutes, I will go in and carefully apply the protector. There is good lighting in there so I can see anything that gets trapped under the protector. Works pretty well for me as I no longer go through several protectors trying to get it just right. I do obsess over the smallest imperfection. Call it OCD, being anal, or whatever. I just can't enjoy something as well if I know there's a flaw. Having said that, I absolutely happy with my titanium Tab S 10.5 and book cover so far.
