The Vision ET is an awful RBA dripper in my opinion. The distance between the coil and your mouth is huge, which means a huge loss of flavor and heat. As that vapor is moving up, it's also squeezed through those little holes below the tank spike, which cools it down even more. Even with higher power the vape from my ET was always cold and flavorless. Then is broke because the design is flawed. The end.
Certain devices vape certain ways, and there really isn't much you can do about it other than replacing the device if you don't like it.
