Yes, it truly is.
There are numerous threads on this board discussing why its a bad idea. In my opinion they can be summarized by observing that spare air is an inadequate tool for the situation for which its is "designed" for. It just cant do what its designed for, namely get a person to the surface during an emergency from depth in a controlled manner. Any situation where it will work as designed, CESA will be perfectly safe.
hey... the point of this thread is not to discuss it being practical. It's to make fun of it. STAY FOCUSSED!
