I bought these for the newest generation WiFi/3G Kindle. I was pretty nervous about applying them (so much so that I put it off for a few days after they arrived!) Following the instructions exactly, and taking the advice of someone else who suggested doing it in a slightly steamy bathroom to cut down on dust, I finally decided to give it a shot. It was INCREDIBLY easy to get them on straight, perfectly centered, and without any air bubbles. I don't notice any difference in reflectivity of the screen. I'm not sure how many companies are out there who make screen protectors for Kindle, but I would highly recommend these!
This cover is a great add-on for your Kindle. I have had a Kindle for many years and since I take it wherever I go, it can get scratched/dirty without a cover. This new cover is better than others I have had in the past. The Kindle fits perfectly and the zippered cover is really great. The Kindle stays clean and protected. The cover folds back nicely for easy reading. I would highly recommend this particular cover.
