I have tried them. The tobacco tastes like the cartos in an Ego kit IMHO. I used it at 10% and prolly could have gone lower. Of course, I used EM in all. The RY4 is the same RY4 being hawked as Dekang, though it is NOT the original Dekang I quit smoking with. A little birdie told me the chief chemist for Dekang jumped rice paddies to Hangsen and Hangsen NOW has the original, but IDK if that is so as I have not tasted them. The 555 tasted like Eastmalls IMO at 10%. They had one named marl and I could not vape it, it tasted of hay at 10% and I don't think that will go away. I believe many of these flavors would be good bases for great tobaccos if they were tweeked but I am not in the mood to tweek too much these days. I have tweeked my own and a few friends everyday vape and play once in a while. Lets just say, I am an old vaper,semi-retired DIYer and like to "vape out" once in a while
This is all subjective, as always, I love anchovies and fois gras , also.
Delicious to one is stinkysockvapor.vom to some. I love to LOL at flavor reviews.It is hilarious to me that someone says it is great and everyone runs. BUT, I suppose one persons subjective percentage could give someone a place to start???
FWIW.......an example: Gorilla juice is a winner in sales and for the life of me I can not picture myself(Nor could I after tasting it) smoking tobacco with bananas in it! YUCKO!
I hope someone else chimes in with better reviews to prove my point.
Happymixing and then happy vaping!
