I have finished the video, and have done even more testing.
My Hammer lock-on stems fit well in the chamber. They also do work, very well. Same for underdog simple glass stems, the thicker silicone is too thick.
Above I mentioned an increase of ease of usage, I find it easy to use vapes if I don't have to worry about particulates find their way onto my tongue. That was my main dislike of the FW along with the loading and entire mouthpiece area. The chamber is very handy, I can already see many ways to improve this device for new users to vaporization.

firewood Please consider putting a screen over the metal wire or whatever is heating in there. Then add a bigger glass mouthpiece that can house the domed screen (if possible), and you could remove the chamber entirely. I could understand not being able to create a glass stem similar to a mini beer bottle where the bottom is removed and the rubber gasket should still be usable. Just an idea though.
This one definitely seems harder to combust, for the video I preheated it for times sake, I feel as if I can just hold and hold and it won't catch a flame. It really is mostly convection, the video will definitely prove that. It was my first bowl this morning and my first time using it with those instruments and it went smoothly. Sorry the abv looks WAY darker than it is, I swear it's actually light brown with yellows. I grinded it further to show consistency but it made it appear even darker. I really wouldn't mind getting myself one of these now that I've gotten a chance to really see its performance.
