It depends on which Fantasi you're using - the genuine Mayasian juice or the British knock off.
I've only vaped the the genuine Malaysian stuff, and I can tell you that it's cold. Really, really, cold. Brain freeze cold. You can't chain vape it that's for sure. It's also all increadibly sweet and a bit arteficial, but it's okay.
Washington Vapes is the place to go it for it if you want the real mccoy. You can identify it by the metal dripper bottles.
Don't ask me what's in it though because I have no idea, so you're taking a bit of a chance. There could be anything.
