I had the case on vacation in use up to 35 m. There were no problems regarding leak -. Not even moisture or fogging. The service works fine - am very satisfied. With the included metal plates can adjust the buoyancy of the housing - works well. The manual is silent located, where to get a new desiccant. Had to look for something. Under the heading ("silica gel"), it can, however, easily find and buy more. The sealing ring can be solved and reassemble easily. With regard to the illumination of the flash and the lens you have to try around a bit.
Buy recommendation.
