So, I did actually have to try reusing this because even though I got into the lowest dust room in my home, I forgot about the cat hair on my shirt. Pets and screen protectors do not go together. So any issues applying for me were definitely user error. being that it only costs 27 cents, no big deal to me. Figured I could test out if it is reusable. And it is! Washed it, able to get the dust and cat hair off, and it still sticks well. Only issue is trying to figure out how to wash it without any water spots on the sticky side. (my reason for giving it 4 vs. 5 stars). Those will create bubbles too. Doesn't seem to bubble other than if there's dust or debris, which would be true for any screen film.
For the function of being Anti-glare, works well. Didn't notice any trouble with the iPad picking up finger touch either.
