i got mine a month ago after some exhausting research about different vaporizers. volcano's are way to expensive and cumbersome, and those other wood ones are gross, to me. i got the extreme and love love love it. both the balloon and the whip are great. seriously people, this is the most awesome thing i have smoked out of. my friends have named it and make me travel with it when we kick it outside of my house. i have not gotten the battery pack yet so it can be portable and used, but i prolly will. i love the remote on it to turn on a fan, turn it on or off. it may seem lazy, but its really really convenient. i seriously recommend this. its half the price of a volcano with many more features and the accessories are cheaper also.
