The best of the Red Bull flavors if you ask me. Way better than the original which doesn't taste good at all. I don't know if I'd say this is really cranberry, it's not very tart and has more of a mixed fruit drink (but not a super sugary punch flavor). I drink this by itself rather than as a mixer.
I have a 7 month old that isn't a good sleeper. So I basically live on this stuff, sometimes drinking a can before I can make coffee. Best idea ever? No. But it helps.
