Actually, pretty much any tank will fit. The problem child is the DCT because of that wide flange at the bottom. Even that one fits without a problem on a lot of lavatubes. One might not fire, and the next identical unit will. For the ones that won't fire, the difference is so minute that all it takes is a very slight amount of center post pulling. I had the very same issue with a Baby Bullet, pulled the post about .1mm and it worked fine.
BTW, nice to see another Tampa Bay area vaper here.
