Been smoking at least a pack a day for 20yrs couple yrs ago bought a cheapy ecig with refillable cartos but gave up then a month a half ago picked up a joyetech 510 t didnt have much knowledge and wanted something that lit up, was analog size and i liked the tank idea and i really like it.it helped me get down to 2 analogs a day and today i just opened my kgo and so far very happy
. I think its good to start with something analog size to make the transition and then move up from there
