Hi, forgot to mention, the OG Dabbler still exists in a small quantity at vaporwarehouse and vb. I believe the Dabbler Heater only exists in this form. You can search Vaporwarehouse or talk to them to get the Inconel heater again. Glass globe is the Ti-Ni wire like the rest. I'll update the site to be clearer on that. Recommended voltage range is kind of forgotten now. We used to care about it a lot, but now we just crank a twist to max if we want to speed up. We've been testing many of these 3 settings batteries lately and find their voltage doesn't really change at all. Dabbler's microcircuit tried to control the temperature, but ended up being too cool for people and got adjusted in the 2nd year of production. So now it seems the temperature of the coil most depends on how much oil is touching it. (and you can pulse the button of course) A giant dab may need max voltage to be warm at all. On the other hand, you may need to back off a tiny dab to not overheat it. You probably are very aware of all that- I'm just downloading info here for anybody else who reads it. It would be awesome if you sent feedback, for sure. I'll let you know if/when we have info we need to know. Testing voltage is complicated, but you can get close if you use the AC+DC setting on the meter. If you have an oscilloscope you'll see PWM happening part of the time. The more resistance you add to the system by taking it apart and installing lead wires, the more the microcircuit will act differently.
