I have to admit it was a bit scary inserting my new camera in this vinyl bag and going into the ocean but it worked, and worked great. Only issue I had was having to restart the camera a few times if the lens wasn't perfectly lined up with the hole for it. Guess mine was perhaps a bit long for the bag (Lumix with 20X optical lens). Other thing that's perhaps not related to the Dicapac is that while snorkeling I couldn't see the screen at all so it's basically aim and shoot. can be hard to use the buttons as well so forget about zooming in and out. Overall it was just what I needed (and the price was right) to document my vacation in Hawaii.
