what with everything in your profile referring to vaporizers, I suspect you are advertising for your own product ... no matter, but it seems obvious, just the same ... I don't like vaporizers, but, I prefer the HerbalAire, and I never had a situation where it's vertical bag 'fell over', etc., etc., ... and, yup, the Volcano is ridiculously overpriced (just like they ALL are) ... :smokin:
