If the next 2 weeks extensively tested :)

Until now I could test the housing only in the sink, and it has made a good impression. I'm going on vacation to check it, but through their paces! If I do not forget, I'll then finish the review.

Update 15:12:13
I used the camera bag on vacation almost every day while snorkeling and I have to say: working properly! I've done with my 6 year old camera really great photos. The camera has remained pups-dry! Even if I sometimes 3 - 4 meters am dipped down.
The only disadvantages are the limited operability of the camera and the lower's view of the display due to the extra reflection.
Conclusion: very affordable alternative to a real underwater camera if you are not a professional photographer ;-)
