Just changed my screen placement from domed with it facing l( Then I cut it so it fit flat instead. Can get more herb in this way and at 4 heating with stem in, then waiting 30s longer after heat up and got huge milky hits. Much bigger than with screen in first domed configuration. Not sure if because more herb, better circulation or both? AVB came out more even dark brown I'm used to, not really dark (almost black) on bottom, lighter deeper in, like before with domed screen. Very impressed with this portable vape now. Clouds as big as old DB desktop.
