I am 45 years old i have smoked since a young kid it was the hardest thing for me ever to stop smoking i tried everything and nothing worked i tried the juul and i could not believe it i do not smoke any more none at all thats good or me i was a very heavy smoker this juul is amazing and i love how small and light it is.The only thing i would ever say is that the juul company should put chains on these to put on your keys or purse i have lost this 100 times i give it a five stars i would love to have a pink juul.
