I have tested it when i have looked for new housing.
I have onli dived with it 3 times.
The thing i do not like is the shutter trigger.
It is more suitable for video, not stils but that is my personal feeling.
Perhaps one can get used to it after more time in water.
Remember that You are limited to only fiew settings,
so it is between diving with the same housing for longer period of time but without possibility to change many settings of any camera you put inside
or housing that lets you to set anything You need underwater.
I have decided to go for dedicated housing after the test, and never looked back. I will just stick to it for longer period of time. (will not change housing form nikon d700 to d800)
