Installed mine yesterday (by the way mine came with 2 screen protectors), I was worried about installing the screen protector but that was the easiest part. I ended up with one bad spot on the armor but overall did a good job. I used the grey and I love that it is the same color as the phone, makes it harder to see where the carbon fiber stick on ends and the phone begins.
The screen protector still needs a day and a half to clear up, but I can already tell that it is going to be 10 times better then anything I have used before as far as oil and finger prints.
Now what I don't like. I was hoping the carbon fiber would have a little more grip to it, to me it is almost as slick as the phone without it. Also even though the carbon fiber stick on is thin I still don't like the feel of where it ends and the phone begins. The hard lines are very noticeable and it just doesn't feel that great. Going to give it time but I may take off the sides and just leave the battery cover sticker on just for the looks of it.
