It's not a cheap atomizer but it works marvelously. First of all, it's surgical grade CNCed stainless so it's nigh indestructible. It's also pretty small relative to other potential choices. I think the real reason is that it's just the right diameter for convection, it's easy enough to build a coil to fill the whole oven--though shorting to the kanuelensockel walls must be carefully avoided, the end result is spectacular. I think whichever way you go, it's important to fill the entire air-path with thick wire. I found 22ga 2x twisted worked best, I only tried titanium but some people use stainless which has a lower temperature coefficient of resistance, and therefore, is less accurate for TC. Finally, though I like the enano stems, I think the stock A2-TM bowl conducts significantly more heat to the load, and consequently vapes more evenly. I was able to one-hit a bowl in an enano stem by torching it just until my herb started to brown on the outside, then hitting it with the Bulli-- but boy, was that irritatingly thick vapor.

If you go the route of the "phoenix" glass atty, I'd recommend trying to wind a coil around the bowl, between the bowl and the outer glass, designed so that air is drawn from above. That way, you get conduction and convection. That's been my dream for a while but I am not motivated to build anything better anymore =)

At home, I use it with an enano stem or gong stem so I can see the herb. Regardless of the bowl in use, I usually load it by sucking up the ground herb from my grinder, or a centrifuge tube.
I actually haven't used those specific tubes, I actually use 5mL tubes since even that's overkill for me, but you get the idea.
