It has been 6 weeks since I have had an"analog" cigarette.........I have an ego plus tons of juices..I recommend it to everyone. .My dad who is a three pack a day smoker just called me and said his e cig came in and for the last 3 days he has only had 4 cigarettes and vape!!!!! It is truly the greatest thing since slice bread.....I always recommend awesomevapor.com for e cigs and liquid...The customer service can't be beat............
