My BP/W rig was "too complicated" for one rescue class I assisted with, so I was not used as the "diver needing rescue" for the scenarios where the diver's rig had to be removed... Good to know that without plastic clips they can't get me out of my gear in the water.
I have a transplate, so I have clips on everything including my crotch stop. He just didn't think to stop and look to see why my rig wasn't coming off.
I'm not sure that it's as relevant for Florida-based divers, because it seems like most state and county parks disallow solo diving.
It is useful in a boat context, I got it so while diving rec boats that I don't have to worry about an instabuddy, but instead have my (little) pony bottle on my side. Particularly since when I am diving recreationally I probably have a camera in my hands, and I want to be more focused on it than wondering where my buddy went in the 30 seconds since I last looked up from the screen.
That being said, no one has asked to see it since I got it. So money well spent I guess.
