We had the Aquapac with the summer holidays on the North Sea, so hardcore: sun, sand, water, waves, salt ... No problem for the bag, great pictures through the shell above and below water. What is really important is regularly wash the Pac, otherwise a layer of salt, the sun breaks and the images can be blurred or incorrectly exposed. Once in the evening when you unpack the beach bags handed but completely, the next day everything again tiptop. Must get used to a little one is only to the operation of the smartphone through the shell and to the less well recognized display, but that's a short familiarization.
