Much to my surprise, the stench/odor/burning smell of mine is pretty much history. That's after just general usage. Really seemed unlikely, so much so that the RMA I requested may get rescinded. I was going to exchange it, but now that would be mostly for the OLED display only. That may or may not be worth the time and effort since it's functionally fine.
The advice to pack it tight, puck tight, is working for me. I loosely fill the bowl full then tamp down pretty hard. That fills about 1/4 of the bowl. That's the minimum I need to get it to work the way I want.
Something to keep the puck at the bottom of the bowl is necessary. That was also good advice given. When I take even mild light draws the puck drifts right up to the bottom of the glass stem screen. I can tell it's there now just based on draw resistance. But the fact that it pulls the puck up to the glass screen so easily says that any air leaks aren't that bad. When it stays at the bottom of the bowl, my vape clouds are at their best. Opening the bowl to tamp the puck drifted to the top of the bowl every hit is a nuisance. But it really works well. Just need to mod a jar, get a glass bead or cotton like others mentioned.
I really get medicated with this thing, but it is a herb hog compared to my original DV or my Solo.
