Review of all of these screen protectors:
I've used a TON of screen protectors trying to find the best one, and I can honestly say I've narrowed it down to ONLY ONE that is worth having.
It very well may come down to personal preference... like whether or not you like the anti-glare or crystal look, and whether or not you care about finger prints or not.
HANDS DOWN, if you want absolutely ZERO FINGER PRINTS on your screen, there is only 1 screen protector worth having, and that's the:
Power Support Anti-Glare
It will not show any finger prints, it looks clear when the screen is turned on, and is smooth when using the touch screen. It applies to the screen VERY easily. It does NOT attract dust like a lot of screen protectors do. I keep mine in the front left pocket of my jeans, filled with lint, and never have anything on the screen or "in-case" silicon case.
Other revirews:
Power Support Crystal: Horrible. This screen protector leaves every mark, smudge, finger print, and dust particle on the screen from anything that contacts it. DO NOT BUY IT. It's crystal, so it is clear and shiny looking, but a real hastle to keep clean. If you're like me, you have just a little OCD to you and it will drive you nuts.
SGP Steinheil Anti-Fingerprint: Comparable to the Power Support Anti-glare screen protector, except it still shows finger prints every now and again. Not bad at all, but not as good as the Power Support Anti-glare. Anyone saying otherwise simply must have never tried the power support one.
Invisible shield: Garbage. Tried this, it began pealing, was very cheaply made, and not thick enough to really protect the screen appropriately. Personally, I thought it still left tons of smudges and finger prints and was annoying to look at.
Buy the anti-glare power support and neer look back.
