Gizmon iCA System Review: More than meets the i! by AlyZen Moonshadow

The iCA case itself is made from polycarbonate and, whilst light, is surprisingly sturdy. The set comes with 2 mock lenses, a thick and a thin one. It took only a few seconds to unscrew the mock lens, unclip the top bit that holds together the two halves of the case, remove the thick foam insert and replace that with my iPhone 4. Less than 5 seconds, actually.
