I am a Halo user and vape a lot of cinnamon flavor. Needless to say, it tears up my tanks pretty badly. I want to get a glass or Pyrex tank that will fit my Halo batteries but have yet to find one that goes on without an adapter. The Kanger ProTank 2 has been recommended but it has ego threading. I have been unable to locate an adapter that goes from 808 threads directly to ego threads. I have found adapters that go from 808 to 510, and adapters that go from 510 to ego. Will I have to use two different adapters at the same time to use the ProTank? Any other recommendations for a tank that will suit my purposes, preferably a smaller tank that will better suit the profile of my batteries than the ProTank?
