Ok....got my shipment of 4 liquids in from Ruyan Direct. I'm using a M402.
Vanilla 18 mg - A very subtle flavor. Not too sweet, and not over powering. Average amount of vapor (nothing spectacular), but an incredible throat hit.
Turkish Blend 18 mg - Strong tobacco flavor. Similar to a Camel analog minus the smoke flavor (obviously). Much better vapor than the vanilla. Exact same incredible throat hit.
Flue-Cured Tobacco 18 mg - Sweet dry tobacco flavor. Very similar to the Kick Virginia Primo liquid I have. Maybe a hint of caramel flavor thrown in there. Same vapor production as the Turkish Blend, only with less of a throat hit than the previous 2.
Coffee 18mg - Very mild coffee flavor, actually almost unnoticeable. I've only tried one other coffee flavor, the Kick Coffee Break liquid, which seems to have about double the amount of flavor. It's not bad, but could use more flavor. This liquid produces the most amount of vapor and a VERY intense throat hit.
Over all I am very impressed with these liquids. For my 4 bottles (120mL) it was 48.50 shipped, and took 7 days total (shipped on 4/15 and arrived 4/22). I would recommend Ruyan Direct liquid to anyone.
