NOT!
I thought this could be a good solution to easy coffee on the go: while backpacking, traveling, in airports, etc.
But it tastes really gross, looks like literal poo, and is quite a sticky mess. I made one cup, took three sips, and that is all I'll ever have of it.
HOWEVER: props to this company for innovating in this space. Keep at it.
My counter-rec for fast coffee: ILLY instant coffee. Tasty!
