It works for sure, but you need to be okay with the way it will affect your screen brightness. If you do use it, you'll definitely want to add a brightness adjustment widget (I use "brightness level" found in the market). Reason why, is that inside or when there is low level lighting, you can hover around 25-50% on the brightness scale with no trouble at all. However, when you go outside with sunlight, you'll need to crank the brightness up to 100%...with this type of protector, the screen tends to become a little harder to see in that environment. But that's the privacy factor that causes it. For me, I've used this protector on several devices and I am used to how it looks. So because of that, I tend to keep my brightness at 50%.
As for touch screen manipulation, it works just fine. After installing it, I'd recommend a quick screen recalibration.
Oh and if you like to show your device off...kick up the brightness to 100%, so the people looking at it won't think your phone is defective. And remember you have a privacy screen protector on and they won't be able to see your screen from in-direct angles.
