i tried it, it's like sheesha! lots of fun flavours.
it definitely satisfies nicotine cravings- if you aren't getting anything out of it, maybe you ordered the cartridge with little or no nicotine.
the slightly funny thing is that you don't really get the sensation of the warm smoke going down your throat and filling up your lungs; it's not the same.
the stuff that you puff out is different, too. it isn't actually smoke- it's ionized mist, so it diffuses out of the air really fast- like the mist from the mist-blowing fans. No smell whatsoever.
but it also feels fresh and clean, there is absolutely no smell whatsover. I have a friend who is very, very allergic to cigarette smoke and i could exhale this one right in her face without her even noticing.
fun stuff! but i doubt i'd bother buying.
it's great party stuff though, the flavoured ones are like miniature sheesha.
