I got a Zagg anti reflective. It was horrible. It created a prism effect that seemed to reduce screen resolution. Ordered a Spigen. It was a model that does not require the protector to be wet before installtion. It came with two covers. Seems to be a hard surface. Does not mark as easy as a Zagg or my previous Spigen on my Galaxy Nexus.
The only problem is during installation with the new method you really have to make sure there is no dust. I mean none. My first try I got two dust specks. These leave what looks like a very small bubble underneath the cover. These do not go away. You have to lift the cover and remove the dust with a provided sticky tape. I am not complaining, just a different install method that once you are used to it seems easier. I think the reason why the small bubbles remain over the dust specks is the cover is quite hard and even a small speck of dust lifts it. So far so good. I really like this cover.
