+1 to the percentages being all over the place.
They also have somewhat concentrated flavors, compared to Hangsen's essences, or Mt. Baker's concentrates. I have not tried TA or LA. It is easy to overdo a lot of their flavors by adding even a drop to 10mL.
Their "
tobacco blend" is good, a favorite of my friends. Black cherry has been described as one of the best cherries. It's very strong and a drop of it in 20mL is great to give the candy-ish taste that's the difference between "fruit punch" and "lots of fruits mixed together".
I like to add a few drops of their caramel to any
tobacco for a nice smooth flavor and the color.
TFA spearmint is above any other I've tried, IMO.
