Well I can say that I am thoroughly disappointed. I was expecting coughing, choking, sputtering, and maybe even puking. None of that. I mixed up some faerie's finest huckleberry in straight pg @ 5%, 10%, 15%, 20%, 30% and 40%. I could detect no change in flavor. So I dripped 3 drops of straight extract on my atty and hit the button not any more flavor than @ 5%. I figure hey you still have some pg in there from cleaning the atty so 3 more drops...nuttin. 3 more nuttin. 3 more and nuttin.
I come from the place where huckleberries grow and I can tell you they are strong if not sealed properly b4 freezing they will taint your meat!!! I guess maybe I should lower my expectations or FF isn't for me.
