LMAO, how exactly are those portable? the ones you've shown are all plug in models and NONE work with hash oils...lets see someone put a dab of oil in the cartridge that comes with that vapir one, it would run right through the disk and onto the heating element. LOL
BTW I used to personally own one of these Vapir one units, used it all the time, until one day the blower motor shorted out and I got a huge lung full of the most nasty, foul tasting, burnt electronic smoke you could imagine... yeah that's gotta be real healthy!
