I used a clear back skin for 4 years on my 4, 4S, 5, and 5S. From Power Support (3) and best skins ever (1).They did a flawless job of preserving the phone from scratches. I did not use a skin on the 6 or 6S partially because I stopped caring and partially because the rounded side made them less practical. What was the consensus best skin for the 6 and 6S? I'm willing to at least try a clear back skin on my iPhone 7 Jet Black. I'd take one that has cutouts/flaps for the rounded edge or one that is flat only for the flat only part of the iPhone back.
