It doesn't look like you're getting much when you unbox the Survivor Core. It's a rubber bumper with a clear polycarbonate rear panel. However, as is often the case, the whole is greater than the sum of its parts.
As well as showing off the back of the phone, the enlarged corners offer enough protection to prevent any damage from drops up to six feet high. Your screen won't get scratched if you put the Survivor face down on a table thanks to its raised edges.
All the buttons are covered – but remain easy to press – and there are cutouts at the bottom for your headphones and Lightning cable, with another for the mute switch on the side.
Offering good protection without adding too much bulk or taking away too much from the iPhone's design, the Survivor Core is yet another good case.
