unflav you just taste the nic, it's most like smoking an analog I have found yet, cartos last way longer. I have to admit after a night vaping 38mg, it's a bit strong. mind you I vaped less last night. I still have some flavoured vapes but mostly drip those and just for a different taste here and there.
it was vapoinsano that got me to try unflavoured, and I've been hooked since. that was 33mg. I tried 25 but was a bit to little th for me. I made a quick mix this time at 38 but going to cut that down some today.
