Down the center is a tube for air-flow from the bottom just like a traditional carto. Off to the sides of that are two bolts that serve as the +/- connections that go up thru the center cap piece. All the hardware appears to be stainless, but I can't testify to that. The center and top/bottom caps are made out of some sort of plastic or hard rubber... possibly vulcanite? They seem to be made out of some sort of bar stock and cut on a lathe. All I know is that this thing works great and I am vaping myself silly with it as I type this. I have not found much info on this rebuildable on the web but hopefully others with more experience will get one in their hands and post some video reviews. If not I may have to do so myself. There is one video on You Tube already but I feel I have come up with a better coil and wick setup than that video instructs. No offense if he reads this!
What did you use for your wick?
Very cool. How does it perform at various voltages? I typically like to vape at 6volt. Anyone try it at this voltage?
