I bought the bag for the holidays and am of course at first been somewhat cautious when it went into the sea. However, the bag closes really from dense and not a drop of water enters the interior. Only when you open the connection you have to take something and leave to dry the bag well or dab with a cloth.
Furthermore, one must always make sure that the lens really is centered and properly in the guide, as the shots otherwise have reflections or the edges of the guide can be seen. For fun shots but highly recommended, especially since the price is right.
