I'm surprised to see such negative comments about the aluball, althought all respect to people's opinions. I've found them really good and I can whip up a shell in a minute or so. I usually use a blender and make 4 shells in one go but if I'm topping up I'll aluball one or two shells more. I don't find that the balls break that easily, I think I've broken 3 since I've been using them over 3 or 4 years. I find I can get a good shell with more or less any kava I want to use. It's starting me wondering what other people are doing with it to get poor results?!
