These screen covers provide that little bit of extra protection for the Screen of your Kindle Fire, they will help your screen last longer and should keep those finger marks at bay too.
Please note: these screen protectors will only fit the Kindle Fire and will not fit any other model of Kindle including the Kindle Fire HD.
You receive 2 of the plastic covers and if you can get your cover on cleanly the first time then you can put the spare away for later when the first cover gets worn out.
In order for you to apply your screen protector without air bubbles, which can be caused by particles of dust, and without finger prints or smears under the plastic you need to clean the screen. Marware have included a lovely little cleaning cloth for you to wipe the screen with. I recommend putting the Kindle on a clean table top, without a cloth on, so that if any static should build up when you have wiped (or are wiping) the screen it won't attract particles before you attach the plastic shield.
Once it is clean, start to peel back the film from the plastic cover and line it up with either the top or the bottom of the screen. When you are satisfied start to press it into place, while removing the film a little at a time - it took several minutes to complete but it worked for me and I was left with a cleanly attached protective shield without any air bubbles or wrinkles.
As a bonus the cloth which you receive for wiping your Kindle Fire screen is also very good for cleaning your glasses - I cleaned my reading glasses with them and a smear that had been there since I got them finally disappeared.
