I found rolling fireball the first time I went in to the store back in early 2014; it was one of their monthly flavors they created. I have tried other liquids at several other shops and none compare to WHV quality, and this flavor is amazing. It is a really great cinnamon flavor and the juicy fruit adds a touch of sweetness to the spicy. I have bought this flavor consistently for almost a year now, you have to try it!
