See I don't like tobacco flavors anymore. All I have is fruits, desserts, drinks. Ive. Used lr boges and didn't have this problem. With the DC I never went past 4 volts. It had to have been one of two things or both. 100% PG or not quality juice. I got it from a well known vendor tho. Idk that's the only carto I had that problem with but its clean no and working great with a different juice. 80pg 20vg.
A follow up on the time on the DC..... I got 9hrs and 32mins of vape time from trustfires 880 mah flame batts ;-)
I don't think all sweet flavors would do this. Gla to hear you got that working good again.
