Extremely easy to use! However, there are a few tips to keep in mind: > I recently bought my Switch and left it in the box until I received the screen protector > I did not use dust removal stickers. I just used the microfiber cloth that came with the screen protector to gently wipe away any dust particles. > I watched the tutorial video once to get an idea of how to actually use it. Then I repeated step by step.> The best advice from the video is to just touch the center after removing the protective film "1". There were a few bubbles which I squeezed out with a microfiber cloth but they disappeared within the next 24-48 hours as the tutorial suggested :-) This is a great screen protector for now. It shows visible streaks or whatever when you touch the screen, but you can easily erase them. I'll let you know if I get blinded from gaming, but when I set up my new switch I didn't notice any glare from the direct kitchen light overhead.
