I bought the Steinheil anti-fingerprint as well as the ultra crystal clear. I first put on the anti-fingerprint one which worked fine indoors but when I took it outdoor, it reduced glare but also made the screen pretty much unusable. So I removed that one and put the ultra crystal one on. Both of them were very easy to put on. The clear one definitely looks nice. I can't tell a difference in the screen indoors and it seems to be fine outdoors like it was without a protector. There is a little traction feel on the screen when sliding my finger across it slowly. Quick swipes seem to be very smooth. And I tried writing a message with Swype and it was no problem. Didn't seem any different than when the screen was bare.
Also, the ultra crystal seems to not show fingerprints as easily as the bare screen. We'll see how it holds up.
