Here is what I think about the Steinhil:
The surface is great, better than it was naked.
No more smudges, glare, having to polish the screen constantly with a microfiber or with my Oakley bag, and I can see my phone in the direct sun.
As far as clarity, clarity is reduced. It is going to be with all of the anti-fingerprint screen protectors. But, it is hands down ten times better than the Zagg, or any other offering on the market. Between my roommate and I, we tried just about every one on the market, Zagg, VZW, Sprint, egay, et cetera. The text and edges on photos are still slightly less clear though. If the ultimate display is important to you, then either go naked or get the CC from Steinhil. If being able to actually use your phone in challenging lighting conditions or fingerprints annoy the living piss out of you, then get the Steinheil anti-fingerprint joint.
The surface is great. Both with the CC and the Anti-fingerprint versions. I've had the Anti-fingerprint one on my phone for a few months now. I put the CC one on her phone because she is inside at work for most of the day. I have swype on both phones, so you can imagine how much sliding your finger across the display goes on, as opposed to just tapping it. IMO, it is better than it was naked on both.
She can't really compare though. As soon as we got her phone, I took it over for the next few hours, and she got back a rooted D. Inc with all the bloatware gone, with a Steinheil CC, in my extra VZW black silicone case, and a ton of apps, lol.
