First time using the Aluball:
I made three rounds -- 1st was 500ml water w/2 TBS borogu, 2nd was 400ml water w/2 TBS borogu, and 3rd was a second wash combining the powder from the two with about 400ml water. I shook each round for 3-4 minutes.
Taste: not bad, very weak compared to the KWK instant. I did add a squirt of Crystal Light drops and some ice, and that made it VERY tolerable, almost tasty.
Effect: not very strong. I spaced each of these about 20 minutes apart. I didn't expect much from the second wash, but I did expect more from the rest. Empty stomach, no worries there.
So next time I will increase the amount on the first one to 2.5 TBS or maybe even 3 TBS, and see how I feel. It's not totally shocking that I would need more because when I was drinking instant, it took me 4-6 TBS of that to get me to where I wanted to be. Not sure what the equivalent of that will be in medium grind, but it sounds like A LOT.
Hopefully, at some point I won't need to use so much... if so, this will have to be an occasional thing rather than a daily thing, because of both time and money.
