i did a lot of reading and watching of reviews on this same subject, I have the black one coming in now!
from what i understand it is one of the best vaporizers out there "well as far as portable".
I have spoken with ppl who vap and ppl who have vap'd, most of them that I spoke with said it does medicate well, battery life is good and it is compact. But that being said alot of them tell me you either like it or you dont.
I'd say if you are going to get one anyways get the pax or if you are trying to save money the di vinci or magic flight are half the price, but imo they are not as concealable.
