In the past, I admit that preheating made me think of conduction, but I found a pretty sweet spot. The nickle setting, and I turn the wastage kind of high, like 42, but temp 350. I get one tiny area a little bit darker than the rest, but not much at all.
This vape is so interesting. At one point, even extraction except one tiny dark spot that was almost burned. Out of the box it worked fine, but as I play around with seeings, I get better.
If playing around with settings sounds fun, I recommend it. It is fun. Lol I'm so high. Been using stem and dry bubbler all night lol. No beer tonight, so definitely a factor to my throat.
The small glass insert for the stem broke already, and it's a little bit of a bummer, but not much. It was nice, but not necessary. It did help cool the vapor when using just the stem. And I did get broken glass on me when cleaning it up. Accidents.
Tip: don't close your teeth together when vaping, it will hurt your teeth.
This vape can pump it out or take it slow. I really like it as an in demand session vape, which I didn't even know I was missing.
