Took these in a hurry. Got mine from the website, I wiped down my DINC, used canned air to blow off stray fuzz strands. I went ahead and did it in the bathroom with the shower running. Don't know if it helped, because I still ended up with one fuzz-bubble.
My thoughts on installation: The greenish plastic that's on the face of the protector was saran-wrapish. When I went after a couple air bubbles, it bunched and tore. In the end, I used the thicker plastic film (from the phone side) and placed it over the places with bubbles and used the squigee to much better effect.
To get rid of the fuzz-bubble, I pulled up the protector with invisible tape, and used another piece in a loop to remove the dust. This worked perfectly.
Only complaint i have is edge around the trackpad not sticking for a total of maybe 150 degrees of the circle, in two seperate spots. Might have been something to do with how I removed the cutout for the button, slightly warped the plastic, who knows. I'll find out whenever i need to replace this with the 2nd one.
It's not as slick as glass...but, well...duh. But it's still pretty smooth. The fingerprints are from about half a days worth of playing. Haven't done any hard scratch tests...but it definitely isn't like a ziplock bag. It was stiffer plastic, not rigid like blister container plastic, but not ziplock thin...My fingernails don't scratch it, and my key with light pressure from a dull edge didn't do anything either.
All in all, I'm pretty satisfied. It's crystal clear, like the name, and you can't tell its there.
It accumulated fingerprints...differently...than bare glass, but it's definitely not worse. I just can't tell if it's better. My desire was for an extra layer of protection for peace of mind mostly. I don't mind fingerprints because otherwise, i'd have to go with an AF protector, and I just don't want to sacrifice the screen clarity.
If you're thinking you got counterfeit ones, I can take pictures of the packaging and contents when I get home, if you like. Do you have any pictures of yours?
