One dares not remove their S4 Nike+ from thy box without a screen protector prepared for installation. So I purchased the “big three” ahead of time for this very moment. Armorsuit, IQ Shield, and Skinomi 44mm (advertised as such) wet install film screen protectors. And the winner, just from opening the boxes and looking at the protectors, is Armorsuit. Why? It is significantly larger and the only true edge-to-edge protector. I had used Skinomi exclusively on my S3 and had gone through 2 packs of 6 over 11 months. Because every 3-4 weeks, the edges would begin to show and the corners would begin to peel. They were not quite edge-to-edge. Looks to be the same close-but-not-quite design this time around too. And the IQ Shield is exactly the same size. All else seems to be the same between the three brands, same finish and thickness. But the Armorsuit is quite larger.
