I ordered a black and ss model and love the flavor of this tank, best flavor I've found with pre-built coil. Then comes the flood, I'm not entirely sure if it's the the tank design or the coils, although the push pull function is problematic because it creates pressure on the center orings. In my opinion the coils continuously cook off liquid once it heats up. So I've modded my coils by using cotton plugs on the upper juice ports of the coil, It hasn't leaked so far. Just be sure the cotton plugs are small enough to fit those tiny ports, and do not stick out more than the orings. obviously you will have to replace the cotton if you want to dry burn the coils. I hope someone finds a good answer, but for now I'm running mine as a hybrid similar to kanger or ecell coils.
