i own the arizer solo right now, i really love it but its enormous and i take my vaporizer to concerts and when people bump into me i just know they're thinking "whoa, that guy has a rock hard boner" its just not convientant to use for outings imo. my friend let me try his pax, i really loved it, super fast warm up time. i dont really use oils, not even sure what concentrates are? i just use ground up herbs, i think thats all the pax does anyway? i know the magic flight box is half the price...pros and cons for every vaporizer i know. i've been looking at pax, the da vinci and the atmos raw and mfb. can i get peoples opinions on what they think i should go with? i really liked the discreetness of pax btw, that goes a long ways, i've also heard its a pain to clean though...sigh. really appreciate any help on this. ive learned so much from FC forums and now i'm hoping someone can tell me what they'd recommend for a portable vap.
