Yeah, so the consensus shows that you should definitely look into ordering some replacement glass for your Subtank if you're planning on using it as your ADV atty. Fasttech has them pretty cheap with free shipping, just takes awhile to get them, so I'd order them now well before you need them
@loucas . Fasttech also has the bell caps which are acrylic/plastic if you want to go that route. They are fairly new, but seem to be holding up well from what reviews I've been able to find. I'm looking forward to getting those myself for my Subtank Minis.
On another note, I've been enjoying this Delta II I got quite a bit. I haven't tried it with the RBA coil, but just with a stock coil, which should be 0.5ohm but all my mods are reading it at 0.6ohms...been running it around 27.5-30 watts, and it's one of the most flavorful vapes I've ever had from a tank.
