i l o v e my Volcano. i just replaced my 3 year old one. Remember when i first tried mine filled with a greedy pig amount. The chronic from serious glued me and my buddy to the couch for 4 hours. It scared me off for a while but soon i came to love it.
Now i never smoke joints and if i do, it tatstes like shit. Ok , maybee Shit is to harsh a desciption, but i am never impressed.
Once you swithch to the volcano permanantly, you start to really taste your herb like you never have before. your buds taste just like they smell.
After a few months, try a joint and prepare to be horrified. your mouth will tatse like and ashtray, the herbs flavour will hardly come through, i kid you not.
as for the temperature - as stated,i very light (hardly visible) mist is true healthy vapours, but a heavier smoke ( 7-8 ) satisfies joint smokers better than the lower settings do. Experiment.
Peace.
