I never used any E-cigs before - let alone seen one. After some online research I ponied up and ordered the Halo Triton Tank Starter Kit and the tobacco sample pack. I received it on September 18, 2013 and set it up and took a few puffs of Tribeca and said to myself "This is it". Just before midnight I smoked my very last cig and crushed up my last 4 packs of Pall Mall Orange cigarettes and took my Bic mini lighters and put all of that stuff in our condo trash dumpster. I have been smoke free every since. Now to answer the OP - I did not want to fail so I am backed up with extra chargers, batteries tanks, coils, and plenty of E-liquid, all from Halo. I have spent so far $433.57 for 5 orders. I was a pack and one half to two pack a day smoker for over 50 years (it's a wonder I'm still frigging alive and it's a miracle that my health is relatively good). So far I have no complaints with the Halo system FYI. I know I'm going to be money ahead in the long run; the ill effects of my smoking are slowly subsiding and hey..........I DON'T SMOKE AND NEVER WILL AGAIN. (Hopefully the damn stupid government won't ruin it for me)
