1) Installation is complicated for someone who has never done this kind of screen protector before.
2) Fingerprint for me is working exactly as before. If I put the finger in the right place for enough time then I get like 100% success rate. Don't even need to press harder than before.
3) I got bubbles... My desk wasn't perfectly flat, so like 30% of the adhesive started spilling out and I think this caused the bubbles, but you can avoid it by doing it in a perfectly flat surface.
I hate having bubbles cos it's a expensive screen protector, but they are not as bad... so maybe in the future I'll try to reapply it.
Hope this helped.
