I dunno - it's been like this since day one. I don't know if it's the batteries and charger, as they get very hot after awhile, like too hot to touch, and they may start burning the herb. So I usually have to stop entirely and let the Box and the batteries cool off. As for technique, I think I'm doing it right - I taste the vapor and keep tasting it and tasting it and tasting it. This is how I've been using it - am I doing something wrong: -push the battery to start heating -after a few seconds deeply suck out the vapor for 10-15 seconds, disconnecting the battery towards the end -inhale and hold, then push the battery back into while exhaling, and repeat -I usually draw slowly until things start heating up, then I suck harder to try to cool things down -especially at the beginning, shaking it isn't enough to dislodge the load - I have to break it up by hand before I can shake it. I do this after every toke or two -after a bit the herb is more dried out I crush it with my finger some more After doing this continually for 15 or 20 minutes the battery gets very hot so I pull it out completely and let them and the box cool down for 5 minutes or so. I do this several times before the heating lamp inside gets very week. Still getting vape at this point, which is like after 40 minutes or more. The herb is less green than at the outset, but not really tobacco brown. The buzz is short-lived and is like an old television when the color starts to fade. The one time that I got a more robust high was vaping the off-white dust that collect at the bottom of the bag and clings to it's sides. Do people who use it have access to serious hydro, or does it work best with cheap dirtweed, etc? Because between this and the Iolite, nobody I know has been impressed with either of them. I did try a Pax recently, which I was surprised to find actually did the trick, and I'm wondering if people who swear by the MFLB maybe are used to outdoor shake or otherwise. I should add that my tolerance isn't super high - my pipe bowl holds less than a trench, and that's plenty. Any ideas or useful advice?
