if your looking at a BC vapo don't bother ,
i just gave mine to kottonmouthchris on here because it sucked .
BC vapo is a conduction type where weed sits on a hotplate n makes vape whether your hitting it or not , no temp control either , gets too hot n stuff tastes like burnt popcorn or peanuts. and is actually wasteful .

a convection type vapo is much better only producing vape when you are actually hitting it . i used to puff about an 1/8 to a 1/4 a day , like lip - no shit . i'm a frequent med. m/j user . now w/ my vaporwarez vapor cannon i use about a tbl. spoon of weed a day . we only havta pack the vapo twice a day . that's a hell of a big difference man .

peace
