Nice as a waterproof case, but any company that suggests you use the same (feeble) battery as a back up light and video camera as your dive computer, well thats just plain dumbass. The fact they use it as a sales tool, placing lives at risk doing so, causes me to suspect the entire product, as the manufacturer does not seem to care a wit.
Suggesting it as a log keeping back-up, well maybe, or to check your stocks while 100 ft. down, yes it would be usefull for that.
Also, everyone who uses clamshell underwater photo cases knows just how vunerable these case designs are to even an eyelash hair across the o-ring, to cause a flood. Your dive computer, in a clamshell? I suppose they might be planning a bluetooth transmitter, for the full 'roulette version'
Honestly, I think you would not find a buddy to dive with. But I admit it does look like a very cool case - If the voice functions work... I want one!
