So far I played with the Hangsen cream, Hangsen V1, Hangsen usa, Hangsen Cherry cigar and Jungle flavorz Strawberry.  I really love the Jungle Flavorz Strawberry. I used it @2% for a add in to Hangsen Cream. It's very flavorful and I wanted to create a Lifesaver's Strawberry and creme saver. I believe I used 3%Hangsen cream. Sadly, I do not have my notes right now. Next mix: lower % of Strawberry to 1.5%. This strawberry is very concentrated. 
Hangen Cherry Cigar: Just like a mix I made from Hangsen Cigar and Cherry. It is exactly what I expected and I no longer have to make my own mix. 5% 70/30 - 80/20 blend and I am happy.
Hangsen USA: What I expected. A 
tobacco (medium flavor). Simple but good.
Hangsen V1: This flavor is not for me. It does have honey notes/flavor. I tried to like it but sadly it does not agree with me. I might use this as a mixer...or rehome to someone who may enjoy it,
I have some Nature flavors I need to try. I mixed the cake batter and spice blend. They smell divine. 
Btw: I did add  one drop of my home made splenda equivalent using ecx splenda powder. (Added to Strawberries/cream flavor).   I mix this with distilled water 1/4 teaspoon to 10mL for this purpose.
