The Retro’s design is intended to evoke the look of an oldfashioned microphone, but we didn’t realise this at first; it seemed more like some sort of skeletal ribcage, hugging the iphone with a dual layer of silicon and hard polycarbonate.
You put the silicone cover on first, then place your now semishielded iphone inside the plastic outer shell to complete the transformation. (the silicone has press-through button overlays for the sleep/Wake and volume buttons, but the inner case is so squishy that we found them more difficult to press that we’d have liked.)
It should certainly keep your phone protected against minor bumps, but if you’re looking for something more minimal, you might want to look elsewhere. the case also comes with an adjustable plastic stand, which offers a choice of three angles for propping up your iphone. Albert Filice
