Doesn't come with any installation aid other than an alcohol wipe and fabric screen wipe not that I needed one. IPad screen protectors are easier to install anyway. Fit perfectly. Not difficult to align with the screen. Once I was happy with the alignment, I used a couple bits of tape to secure the screen protector on one end while I removed the film of the adhesive side. No bubbles. No dust (fabric cloth wasn't much help).

So far, no scratches or cracks. The iPad has taken quite a few drops and punches (angry nephews will do that). Although it's pristine condition is helped with the sturdy iPad case (Miesherk).
