Had one for about a month then got sick of it, works well for quitting smoking though you end up spending tons of time fucking about with it and refilling and recharging and replacing dead parts. non-stop smoking it indoors, outdoors, in pubs, restaurants, clubs, any time any where is probably putting stress on your lungs and throat which otherwise you are only doing while smoking cigarettes. Went from smoking like 6+ cigs a day to smoking vape nicotine every 20 minutes no matter where i am, so it became too annoying of a habit and i had to stop that, i didnt touch cigs in that time though so it does the trick if thats what you care about. I was more looking for an alternative to smoking tobacco without actually having to give up smoking, should probably not have bothered! Agree that they shouldnt be allowed in public places, it bugs me now that like 1 in 5 people is puffing clouds every time i go to a bar or a club even when i was using one i would be discreet...
Also anyone buying zero nicotine stuff and joining in, why dont you just go buy some jelly beans or popping candy or something they taste better and are cheaper and you will look cooler.
