i haven't used on myself but the extreme vaporizer looks pretty sweet! i'm thinking about getting that one for christmas myself. it has a remote control, 3 speed fan and a 3 foot hose with 3 glass mouthpieces. it also comes with two bags (ballons). if you look on youtube there are a couple of videos. check it out. for $279 it does a lot. oh, did i mention that it has a battery pack?
