Ok so guys. I have some parents and family members that wish to quit smoking. However, they have tried my tfv12 but they dont find it satisfying because its to strong. Most of them have tried vaping pens, but they dont use them. Does anyone here know of a good device for long time smokers? Im thinking mouth to lung hit. Important that there is a good nicotine delivery. Also important that it is not big, just a little mini or some kind. Just s simple device where you use the same teqnique as smoking a cigarette important that it is seal proof! Forgot to say that the batteries needs to be replaceable (probably 18650). Also important that the hits contain fullness and power.( i had a kanger topbox that was way to weak)) maybe a dual battery device Reasonable coil pricing is also a + As for juice, i was thinking DIY 50/50vgpg 3mg nic for starter.
