i looked online for 3 days trying to figure out which to buy/start with. Came to the conclusion after tons of research to buy the titan 510 starter kit from TW. Im a pack and a half a day smoker and the wife smokes too, probably 3/4 of a pack a day. so were both gonna try vaping and try quitting analogs. So anxious for it to get here in the mail so we can get on with it and save money and get away from the tar filled cancer sticks. Should be today or tomorrow! I dont even have any of it yet and already want to start mixing eliquid. HA
