Hi, I just tried one of your tanks and am very disappointed at the volume of vapor compared to both large and small smileomizers. The same goes for 510 and Ego tanks, clearomizers, etc whether I use them with your battery and a thread converter or the 510 battery. Nothing else works as well as the smileomzer and your auto Zeus battery.
If only you made the smileomizer with a smaller drip-tip style tip and replaceable coil there wouldn't be a reason to try all the 510 stuff. The Ming vase tip is better, but not quite there yet.
