Smelly box
Been using this tank for a week now. Very decent solid tank with buttery smooth threading. Nice dimensions, not too high. Not too ugly either. The 5ml juice capacity is just enough for me, for like an hour. It smelled terrible out of the box, like oil and burnt plastics, so i had to clean it thoroughly, a few times even.
Disassembled and cleaned, rubbing in all o-rings with VG
The juiceflow is much better compared to the V1. Away with those stupid pins that were eager to disappear into your sink. No leaking whatsoever after several build. The topcap screws off very easily, which enables you to fill the tank without any hassle, the tank has huge holes to poor your juice in with literally any bottle or dripper.
The airflow is pretty much like the V1, very very airy, but no condensation. And smooth(er) too, no whistling in any position. There's the wider and smaller section again, which enables you to flow somewhat reduced air over your entire coils, smart construction. The builddeck isn't very large, which restricts the size of your builds. When you fully open the AFC it might just be too much for even the largest builds possible on the velocity deck that came with it. Maybe get the postless deck to take full advantage of the max airflow.
The driptip that came with it is nice with a very wide bore, but just a bit too short for my taste.
Kanthal build
So far i did several builds: SS316L, Kanthal, Alien, Half Staggered. Slightly muted flavour, i might have to grow into this tank. When you position your coils vertically right between the postholes they line up perfectly with the airflow. I noticed a tiny bit of flavour improvement when lifting the coils a bit up, so that the airflow goes slightly underneath first.
Combing and trimming some more afterwards
Reducing the airflow and replacing the driptip with a narrower one, makes the vape a bit more dense, improves the flavour a tiny bit too. Not jampacking the deck with wick helps too, leaving a bit empty space underneath the coils, let the air flow through and you get better flavour.
Jampacked with wick -> muted flavour
This tank is a mix between the Boreas and Griffin, with several design aspects of the Plus, topped with a Merlin-style driptip. If you don't own an Aromamizer yet, i'd recommend this one. This Supreme V2 has now almost replaced my Boreases eventhough i get better flavour from those so far.
