Despite the expected decrease in image quality through the case I could find no faults. Videos are wonderful - at least on the HD-ready TV was a treat each individual pixel, full HD, I can not unfortunately play. Also the pictures I am completely satisfied.
The plate in front of the lens is indeed susceptible to fingerprints, but the solution is not far: Wipe and breathing on his sleeve, it had repeatedly tried and each time can find no residue.
Toll is mainly the recording on the surface: In the lower half of the slightly cloudy but beautiful green river; in the upper half of the radiant sunshine; both separated by the living water surface :)
A quarter star goes off, however, as you have to arrange the hand strap for the housing of the camera.
Now you just need one thing: A matching float because should drop the camera with an unhappy day in the Rhine, it was the one with the underwater pictures.
Conclusion: For those who like to make photos or even in the water, a must, it is not only healthier for camera and nerves, but also allows some pretty gadgetry!
