I have gotten this email from smokemachines.net....wich brings me some doubts about this machine. i asked: then i got this anwered: this sounds very fishy. why? because the description of that mail back sounds like im doubting between a Fazer(the unique) and a hazer(the MVS) although the unique uses hazer fluid. I hope you guys can help me out. i really want the fog to be as much invisible as possible. And Fazers....are not hazers.
