Ok, so gave the aluball a good testing. Was able to fit 40 grams in the ball, but I wouldn't suggest it. After shaking for about 10 minutes I separated the ball and about 1/3 of the kava in the center was completely dry. I know I went above and beyond the recommended amounts, so I'm not the least bit upset by it. In fact it still made a respectable kava beverage, albeit a little light. Great device! Anyone who wants one shell of kava, this is for you. If you're a kava hardhead, or looking for a stupidly strong beverage, then you may want to stick with traditional prep. If you're aching for a shell, and don't want to make up a whole batch, get one. It's worth it.
