Does as it is intended to do, and that is to protect the camera.
I opted for this because it was a hard shell, unlike other cases for small cameras which are soft and have unexpected consequences. Like when the case comes in contact with the on/off button on my Cannon camera, and the lens tried to pop out inside the case.
The hard shell of this case protects, not only from dirt ingress but inadvertent knocks.
Any smell from a new product is inevitable and always disappears in no time at all.
