Pretty upset when I got this I tried it right away and there's no smoke that comes from it there's no smoke and I need some smoke to come out of it when you blow it out of your mouth and none does and so I asked him if I could return it and they will not get back to me I have not heard a response they keep asking me how I like it I keep trying to tell him I want to return it but then they don't respond to that. Oh I would recommend staying away from these folks they might have good intentions but they don't have any smoke.
