Got me a used IV, and I'm more or less impressed. It has the same boffo, high-quality ceramic heating element the Magickwand has, which has better than average flavor IMO and the ability to give big hits. The amount of "choke" on the IV seems about halfway between the MW with top capped and then uncapped. Big hits are pretty easy to achieve- I do wish the normal bowl was larger however. My heating element is mounted a little off center, but it's adequate to be annoying and the glass bowl actually clinks and rests against the metal, which is kind of a bummer. Big hits though, and quite inconspicuous for say a drive with the cap on. I wish the dial were a little larger, and I wish the whole unit could get hotter- I think it would be too cool for most concentrates. I also wouldn't mind if the whole thing were 3/4 scale. Do we know if the airpath is separated from the electronics?
I'd say 8/10ish at its price point for a home vape. A lifetime warranty might bump that up a point in many people's mind.
