It seems like almost every time I vape out of this, I get a different session. What I mean by that is sometimes I will put the same amount of herb and hit it the same way and I get different size hits. I sometimes do the cigar technique and I get a nice big cloud, then the next hit I won't get anything. I only use the transfer wand. The other technique I did was turn it to like 2 or 3 and hit it really fast, I got a couple nice rips last night doing that, then tried it again today and didn't get it. How big of bowls do you guys pack in the wand? I usually do around 1/4. Usually for my first 2 or 3 rips I would get very tasty and huge hits that would kick my buzz in almost instantly and would make me really warm, lately I haven't. Maybe my wand is too dirty? Not sure.
