http://www.vapecritic.co...s/volcano-vs-herbalizer/There's a pretty good review there.
I also vape, using the Arizer Solo (so there's no bag or anything, it's just a straight inhale from the heating element). I know the key is getting the temperature as high as possible without burning the spice, when you turn it up to 445F what does it smell like?
I'm not sure on the actual temperatures but I can smash through into hyperspace on the 3rd setting and it goes all the way up to 8 (AND there's a layer of tin foil between). I found the key to be leaving the vaporiser on for a good minute or two before actually taking anything from it, this way I'm sure that all of the spice has turned to the brown sticky goo and the first hit always has me to the point whereby I'm struggling to take a second.
I clean mine out quite regularly, and I always put it onto full temperature afterwards to burn off the remainder of the gunk that's in there. It smells like burnt oil at this temperature and doesn't have any DMT smell to it. After you've taken your dose and there's still vapour coming from the pad, what does it smell like? Is it vapour or smoke?
