Expensive, but the content is more expensive)

What I like very much:
+ Accessibility of knobs perfectly
+ Holds tight!
+ Very stable
+ Perfect for Canon S95
+ Possibility for diving weights (but way too expensive!)

It's a bit unusual, the first time to film in 19 m depth in salt water (for photography simply lack the technology as additional lights), but after some acclimatization it works quite well. Strong buy recommendation!
