Zagg HD (case friendly)
Bought the Zagg HD (case friendly) at the beginning of February and love it, not a single problem with it. It keeps the look of the retina display and protects the screen. It is case friendly, which means it does not extend all the way out to the edges of the phone, but pretty close. Helps keep it in place and no bubbling around the edges when putting on cases. This particular model does not have the orange peel effect that the regular zaggs have either, very clean look. It does smudge a little, but usually a wipe on the shirt takes care of that.
I bought this from a zagg stand in a mall near me (zagg.com search shows locations near you) and it cost 19.99 + 5.00 install fee, but product is covered with lifetime warranty. 30 days no charge w/receipt if something goes wrong with it. After that you pay a 5.40 install fee to have replaced for life. I had to utilize this today because I had my 4s replaced @ apple store. Went to stand and they gave me a piece of paper to fill out and have the protector put on when phone is swapped out, just brought it back and they put on a new one for me. The gentleman also informed me that you get the same initial 30 day window each time you have it replaced. So good customer service also.
sorry if I was a bit wordy, I just really liked the product.
