Basically everything that was PEEK in v1 is now ceramic in v2.
The glass stem will now also be ceramic which would make it more drop proof. I've smashed a lot of glass stems myself. hehe
Since the whole base is now ceramic, we have opted to remove the glass insert to reduce on the parts produced. So the part that holds the flower is now zirconia ceramic instead.
O-ring placements are all the same as v1.
I will try to recommend giving out extra o-rings and mesh screens for V2. We might be able to ship from Dubai instead for the v2 release.
For the custom made screens, yes they will definitely be thicker for the next release.
