iPhone 5/5S metal back case surounded with silicone frame (black) is a superior coverage protective case and feels solid in hand. The plate is made from quality aluminum with silicone attached to it (nice combination to keep the weight minimal).
The rubber membrane latches onto the iPhone 5S, securing the edges which are most susceptible to damage on drops/knocks etc. The cover has a smooth machine-buffered feel to it. The case fits snuggly like a glove.
