I'm currently rocking the UAG featherlight composite case with a Skinomi Techskin Sccreen Protector. Personally, I think the techskin has done a good job of protecting my device. It doesn't have terrible rainbowing, in fact hardly at all. For 8 dollars, for 2 protectors, it isn't a terrible price. I've had this protector on for 2 months, and it does well with cases, though the Supcase UBP squeezes tight and causes mild stretching. The protectors are wet install, and there's no better phone equipped for a WET installation. I wish there was a tempered glass or even a fancy nanofilm or rhino shield, but I'd much prefer the clear rubbery protector over a glass, faulty-sensitivity, painted protector any day. I wish they made REAL tempered glass protectors for this phone that had adhesive all over. I don't understand why they don't. My G4 had a curved display (concave as opposed to convex) and those worked just fine. Come on MFGs, you can do so much better than this. I'll be waiting.
