Excellent! I accidentally bought 6 mg on a juice order last week when I actually vape 3 mg, lol. I knew instantly that I had bought the wrong level. With subohming the nic overload is instant!!I'm only at 20w so far ...I'm taking it slow...but I'm thinking I might get up to 25. I cut down on my nic from 18 to 6 so it's not harsh...just trying to figure it all out
