ya, the BC (Bad Crap) vaporizer sucks, infact if it has a brass bowl in changes chemical structure...u will waste away all your weed with that thing... unfortunatly there is so much trashy vaporizers out there, I havent heard of any consistant good vaporizer for less than 400$.. in my opinion, the AroMed is the best choice for a vaporizer, it has no fans (less things to break down) and u control your own air speed with the same results.. its the no BS vaporizer, no dang balloons either.. VAPE ON!
