After reading the concept and seeing the product in use i'm much less skeptical than I was at first. I'll step in line for one also this is actually a great idea! For my on the go kava, I'll pre-make a big batch then bottle it accordingly, hoping to have enough to get me through an event or situation. usually Although, carrying around a "smartwater" bottle filled with muddy brown liquid seems a little odd and makes me feel a little uncomfortable occasionally. I like that it looks more like a nutritional shake type container. fits in more with the "protein shake" look and less like for someone to make a weird face and go "WHAT ARE YOU DRINKING?"
also, i'd probably dump the leftover root from the ball into a ziploc bag and put it in the freezer for later. enough uses of the ball and there's a decent second wash to make a batch go farther. I've been freezing leftover root on occasion to make it go as far as possible. always get at least a little something from it.
