Besides the obvious, one of the reasons I like Kindle is its design so I did not like the idea of applying any supplements that could change his appearance.
But due to the one accident, I decided to give a chance to the one of screen protectors and while on business trip I bought Moshi AirFoil Screen Protector.
I was pleasantly surprised with this certified Kindle accessory that can be used with multiple Kindle models - Paperwhite, Original, Touch, Keyboard. Its installation on Kindle screen is easy - in package you'll receive a cloth to clean your screen, then you need to peel off the first sheet, roll it carefully over the screen and then push the air bubbles out.
In package, beside mentioned cloth and applicator one screen protector is included, so there is no need to worry for some time about fingerprints or scratches on your beloved Kindle.
If you are OK to change a bit the look of your Kindle in fear that your screen could be ruined I can recommend this screen protector.
