Hey! I work out in our factory in Shezhen. We have an entire room here dedicated to curing the silicone. First it goes through a boiling treatment in a big crock pot like machine, then into an autoclave for a secondary cure. The units are also ran through a burnoff cycle here at 430 degrees for 10 minutes before being packaged. On top of all that, we only use high grade, heat safe silicone for our seals. I think the issue was never so much visible offgassing at is was people noticing flavors that they thought shouldn't be there, and didn't give the unit time to "season." I think it's fair to say in most cases, if they took the time to actually use the unit all the concerns subsided because of the amazing flavor the Ascent can provide.
I have picked up units straight off the production line and used them before, without a burnoff or anything and never experienced any funkiness going on, and I'm here because I'm a stickler for that stuff haha.
I hope this gives you some peace of mind, and if you have any questions please feel free to PM me.
