I did not purchase this screen protector to protect my screen from scratches, but rather to cut down on the glare and reduce fingerprints. I have PIN to drive enabled so my screen would quickly get covered with fingerprints.To install, I cleaned my screen, turned off HVAC in the car (figured this would cut down on dust circulation), cleaned the screen again, and then followed the installation instructions. The frame is nice - it makes installation quick and easy. I can't imagine being able to properly line up something this big without the use of the frame. After removing the frame I found that there were A TON of bubbles behind the protector, which took quite a while to push out but I did eventually get them all. Unfortunately despite all my prep efforts I still ended up with a tiny speck of something between the protector and the screen, on the right edge just before the screen turns from display to black border. I probably could have let this go and nobody except me would ever notice it, but it really bothered me. A quick Google suggested I could peel up the protector and use a dust sticker against the back of the protector to grab whatever was stuck there. I gave it a shot, using the sticker against both the protector and the screen, being careful not to touch the screen or protector with my finger. Initially it looked like I had actually made things worse because it kind of smudged the adhesive behind the protector, but after smoothing it out again with the provided squeegee, everything looks great and no more tiny bubble! I doubt this would have worked if the speck was further from the edge, but it's worth a shot if you've got one close. So remember, it is very important to spend a lot of time cleaning and checking the screen beforehand, because it is huge and you can easily miss the smallest speck that will lead to a permanent bubble!Now that the protector is on and the bubbles are all worked out, I love it. My finger glides over the screen much more smoothly than before, no glare, and ZERO FINGERPRINTS! As expected there is a very slight reduction in clarity but it won't be an issue. I just increased the brightness a bit and it looks great.
