@jdent3 - I have been religiously looking for off-gassing since I started testing these units. I've done some heat beat downs on both the analog and digital units at the highest temp starting with un-boxing burn-offs and haven't run into any off-gassing. I've done the flashlight beam test several times as well as sniff tests and came up empty.
@jdent3.... you and
@priestsmiler noted the black oven streak and I would love to hear more about them. I don't have these streaks in my two units so I can't do any testing. When the streaks were first brought up I initially thought they were tiny, powdery, blackened ABV herb remnants because I had some in mine but mine cleaned right up. Maybe you could do us all a favor.....
The link below will take you to the contact page for the manufacturer. If you would pose your questions about the black streaks and what the gold colored metal is I would really appreciate it. I'd try to find out myself but I don't have the black streaks in mine so I could only ask about the gold colored metal. I've used the contact page a few times now and they respond to your email address in a few hours. When they respond to your email address you'd be able to send them a pic of the black streaks.

@b0 - I think the unit, for this type of form factor, is one of the smoothest I've run into. Maybe
@stickstones could answer whether this vape heats faster than a Pax2 or is smoother than a GH.
