Hey ragno, for sure I do the same - sometimes with a meter of silicone pipe. Like just now, with a mixed elbow of dusties and some ground up herb on top. Really puts the extreme in the Q !
You can't match what this thing can do by combusting, not with the grade of bud I have with my tolerance [not that great and pretty high]. It is insane what is capable of with such a small amount of material and this device really sets a good starting point for experiencing that.
In general though, I think it's either unsafe to use this device upside down, or I have broken something internally in my own device..

Somewhat off topic but possibly of interest; I've just spent way too much time looking at the Sublimator, and have read/watched the details of its workings. It uses an atomizer in addition to a very evenly heated non-forced air chamber to apparently 'atomize the vapour' , from what I gather, that means to re-vaporise more efficiently the oils, and break the larger parts of the vapour up to a finer consistency generating more cloud, and more potent hits.
Has anyone here tried one of these things? It certainly sounds ridiculous, but it does make some sense.
Seeing as the EQ is a fairly stable and effective heating device, something like what is in this image, but inverted and plugged into an EQ, could really change the game of vaporising..
Do you guys think dual vaporisation is worth considering?
If you immediately heat up vapour as its forming, does it increase the volume produced?
