I’ve never used the ‘official version’, but a friend who loves trying out new novelty apparatuses bought a cheaper version at the flea market for $15, and so I got to try it out.
It worked decently and hit well, though all your observations about the lack of practicality are totally spot on.
Then of course, like a month later he dropped and broke it.

Personally I’ll stick with my good ol’ mini-bong.
