Simply put, the Teflon-coated back just feels and looks a lot better than the iPhone’s—now crappy looking, I admit—plastic back. The Hero’s polytetrafluoroethylene—the technical name for DuPont’s Teflon—coating feels perfect in your hand. It doesn’t appear to get any skin oil at all. No greasy fingerprints, just a perfect matte finish no matter how much I touched it.
It feels and looks like a white thermal tile out of NASA’s shuttle.
