I have one of them
It's pretty cool.
It has a decent amount of drag though. (nothing that makes it a deal breaker though.)
Also, the online has downcut slits, and an open end, so it doesn't entirely function all the time.
I think I have a vid of it up in the bubbler bonanza thread.
There are a few pics of it too.
Edit:
It's not too hard to empty, I just turn it upside down, and blow through the downstem part.
That forces most o the water out pretty quickly.
It is a bit difficult to clean, but no moreso than any other
triple chamber piece.
I've never noticed the base to be particularly unstable.
It cant sit there with a solo on it, but it should still stand after a light bump. It's not like this thing is gonna spontaneously stage dive
(that weedstar double showerhead on the other hand...
)
Filling it is real easy.
I put water to essentially fill the bottom chamber, then give a nice stiff pull and the water will bubble up and into the trees
