now come on now, dont lie, u didnt buy it coz u thought it was gona be a piece, obviously it works good and has developed a good reputation, and as far as i am concerned/......... if the aluminum element is not a threat, and the fan is of a certain specialized type, then i think the volcano would be a great vaporizer, but i havent looked into it that much so i dont know, so provided that these things were not an issue, it would be next in line behind the AroMed... and just because it is next in line, doesnt mean it is last in line.. i have used some of the others that are way down the line, infact the there is a large gap between the front of the line and the rest of the line,so why dont u look into these things? these are valid concerns, and if u find no threat, then u can come back and call me some more names...
