I just built my MT, and holy crap! This thing is like no other tank I've ever had! It chucks out more flavor and vapor than my rdas! I just put a simple build in it, dual 26g, 5wrap, 2.5mm with a LOT of KGD. I've got to stop doing this in the house. My front room is seriously fogged up! I'm using my IPVd2 at 58W, and it just is unbelievable. I did at first pick up a little leaking at the air holes, but it seems to have stopped. But I've already blown through over half a tank. For sure, I'm going to get serious about DIY!
