Chocolate flavor is god awful in my opinion. Who knows, you might like it- taste is subjective. But I opened the bottle and sniffed it, thought it smelled great, filled my tank up, then had to dump the entire thing into the damn bin.
I can't put my finger on why the chocolate flavor was so gross, but it was not sweet or milky, and had a bit of a chemical taste to me.
I had to replace my coil too, because the chocolate flavor wouldn't come out even after cleaning.
Vapor production was good though, no throat hit. Raspberry flavor was alright, even got a bit of donut. Just wish they had left the chocolate out completely!
