For what its worth from Arizer Support:
"Yes, all new appliances/products have the new product/appliance smell and need to burn off any residuals from the packaging etc.
Rest assured no off gassing or fumes will occur with the normal use of any of our products; All structure materials used inside are safe non-toxic materials and are heat rated to much higher temperatures then the heater can reach and manufactured to ISO Quality Standards, plus CE, FCC, and RoHS certified. We have carefully sourced our parts from all over the world and have gone to great lengths to source and use only safe parts, from glass to silica free ceramics, there are no glues, the pcb's are lead free, all accessories (hose/tubing, bags/balloons) are all medical/food grade & temperature rated.
We perform comprehensive testing on all of our products and components to ensure they are completely safe for use by us, our friends, family, and consumers alike. After some use with your herbal material the new smell will fade away and there is nothing to be concerned about with your XQ2 unit.
Just make sure to rinse the hose/tubing thoroughly with hot water so that it doesn't absorb the taste of anything you used to clean it."
I also found this kinda helpful, going from the Solo II I'm not used to the huge bowl so him packing tips are helpful.
In this video I will show you the Arizer XQ2 and a couple of tips and tricks to get great performance from this vape. The Arizer XQ2 is a delightful upgrade ...
