I have to agree I am one of the first ones to have done a review on the CC Steinheil back on May 15th

I am pretty rough on my cover and I still have the first one I applied, it doesnt have so much as even a tiny scratch on it, it looks exactly like crystal clear glass, I work in the garage with metal, saws, drills etc ... work around the house and dont hesitate, even with dirty hand to use the phone ... I put a wet install Zagg on a friends Moto Droid and I really have to ask why would anyone use one of those? just complete trash, he switched to a CC Steinheil and its a world of difference.
I do and currently have 3M protector film on the front of my truck, which is exactly what that Zagg stuff is (albeit they use a thinner grade), for a car or truck, you cant beat it ... tough install on a vehicle but I have had mine on for going on 3 years and its still perfect, but the orange peel like nature does not make something that would be great for a small glass device (optics).
If you have a good install of a CC Steinheil I can see zero reason why someone wouldn't like it ... it looks and is close to have one naked feeling that can be had imho, its made for optics is probably why, not made for the front of a truck or car.
