Vaporents

The yellow and black thing is a box mod (not sure what the model is called), powering a BAKx by lamart with a heatsink between them so the mod doesn't overheat. If you look closely, you will see the glass tube that sits within the wooden thing (aka the BAKx). That gets heated up by a flat coil that's wound around it. Once you put in the bowl part, the inner tube and your herbs and/or concentrates of choice will heat up. When you pull on it, the air almost only passes hot glass (also a little bit of cool wood) and it puts out densest, most instant vapor I've ever seen from a vape. If you check my profile, you'll find a video of the thing aswell!

I'll refer you to my other response and add that it's pretty much all I use since I got it about 2 months or so ago.
