How does it compare to 10 minutes of kneading? I've been on the fence because it sounds like I'll have to pay 50+ dollars to get it to do what I would want it to do; and I am super happy with my $7 Kavafied beginner's strainer bag that I've been using almost daily for a year and a half with no problems. It would be convenient to be able to just shake up some kava in a couple minutes, but its really not that inconvenient to just knead up a batch; and if its gonna be more expensive and also a weaker mix, I'm just not sure if it is worth spending 50 dollars on an Aluball system.
