The resulting case is waterproof and protects the delicate camera from scratches and mild shocks (i.e. knocking over on table, banging around in your backpack/daypack). The case is lexan (polycarbonate), a pretty tough material, but still, dropping it onto a concrete floor will probably break the *internal* mechanics and glass of the camera due to momentum, even if the exterior will be largely protected. A friend cracked the glass of the LCD screen on his camera, which would not have happened if he had it in this case.” – Link.
