So I have finally decided, with the persuasion of my girlfriend to switch over from combustion to the vapornation. I have decided on a portable since I commute to school and currently still live with my parents. I have narrowed it down to 4 capes: 1) Arizer Solo 2) Pax by Ploom 3) VaporBlunt 2.0 4) Inhalater XP I don't really have a budget. I don't mess with loose batteries, the only extra pieces i would like to be carrying around would be extra duff for more bowls. My main deal breakers are: Odor, Ability to conserve material, and Durability. The Odor is not too much of an issue because I can always go outside to use the vape, but then stealth would become an issue, so I guess those factors mirror eachother. Hopefully someone who owns a few of these or even just one could give me some insight on which would be best for the situation I'm in. I'd like the one that gives the least odor as well as the most bang per gram. I also don't mind any of the designs except the glass stem of the arizer solo, but if it is the best I can deal.
