A little over a year ago I tried the 510 manuals with the foam filled tips, those quickly got replaced by the ego-t's, after the attys started tasting bad went back to Marlboro's. Now Im giving it another try. Ordered a couple ego-c kits and some caramel tobacco e juice. Better than the ego-t but still not the desired effect. Broke down and ordered a couple ego-c twists and a couple nova minis. All I can ay is wow, this is the ticket. Now to find a one stop shop for my e-liquid. Tried sweet-vapes and to subtle even with extra flavor. I see a lot of positives for Kickbassvapes, maybe ill try them next.
