I don't understand why the Vortex hype webpage needs to say things like; "A=
ll other brewers don't do anything that a bucket with an airstone cannot do=
, meaning you are paying for a fancy mold and maybe convenience and a large=
r bucket. They don't circulate, they agitate"

i do not like them i do not think that that unit will provide much flow. T=
here is too much surface area and not enough depth. It will be a very slow=
 subtle vortex, which is neither good or bad, just making an observation...=

ce... and the bubble diffusion does nothing for adding O2 to the h2o... it =
