I still love my EVO and the Sub, but for convenience I prefer the evo. - I feel a lot safer using it. - I don't have to adjust the temp to maximise my extractions (whereas with the sub, i'd have to wait 5-10 for the sub to change temp(up or down), to really get the most out of my herbs.) - I also love that I can bring my evo along with me easily when I go visiting to a friends place or whatnot. with the sub i'd have to wait for it to cool before I can pack it up and that takes like 30 min or so... "ain't nobody got time for that!" because of this I find the sub hasn't been used as of too recent. It's still a rockin vape though! for me though, the EVO just has the edge because of all of it's convenience on top of it's performance. you are correct, I think the sub is just a vape really too. It's unique, but it's still a vape. regarding the oil it produces from it's use. the inventor called the oil "sublimate" and it kinda just stuck. don't think of it as the scientific definition of what the word means. rather, a name to call something that isn't quite kickass BHO, yet it's a darn sight better than the standard vapor reclaim oil that I make. so it kinda needs a new name to refer to it as.
