I tried using Matt's shallow bowl with my alumina cup, and as expected the air coming in below the rim of the cup (see where the holes are?) cools the cup, unevenly, and messes up the temp control.
In the black e-bay units I got from Keepitmovin13 the cup drops into a deep bowl, and the air is drawn in ABOVE the cup, and that works very well, the cup retains temp nearly at the same temp as the donut itself. I'd say the ability to choose where/how you draw in air, like in the better RDAs, would be a great future feature.
Advantages of the cup insert:
- No messy gunky donut, the bowl stays clean.
- Excellent TC, very even temperature across the whole cup, oil boils off neatly.
- You can easily fill and clean the cup outside the atomizer chamber. Prepping the dab is simple.
- Drop the pre-filled cup in after the donut is at temperature, no juggling w/ dabber, carb etc.
- You could keep different pre-loaded cups, just drop one in, like a fresh mag, drop out the empty and pop another one in. Keep a high CBD one ready as antidote in case someone overdoes the THC and gets all freaky ;-)
I was looking at the Bolt and all these other packaged e-dabbers have very high and uncontrolled temps. The Bolt lists 2 settings but nothing like specific temperatures. F'getabaddit. We want good temp control, much more controlled and economical.
I just vaped only the lightest 360 deg fraction from some Tangie Cookies oil, a wispy vapor, I wasn't shooting for coughing out a barn fire. But wow. Just focused and wide awake, the room and everything just lit up. No confusion, no anxiety, and no sedation. Very different from a full heat dab. About half the BB remained, could have saved it for bedtime, but just torched it off.
