We have been testing and talking with other users.
If you are using our tanks and our atomizers,
We have noticed that when taking your drag, it is best to keep the ecig pointed down.
Keeping it horizontal, may leave the wick tip unsubmerged and then start sucking air.
With the eGo-T system, each drag you take, will actually vacuum fill the reservoir with more liquid.
If the piercing tip is not covered in liquid, then it cannot draw up more.
Also, if you control your airflow with tightening the atomizer on the battery.
Make sure the tank is fully secure.
Taking "dry" puffs (without pushing the button) will re-wick more or extra liquid into the atomizer to allow for
a nicer, more flavorful hit.
2-3 should be plenty, and any more may flood the atomizer.
We do recommend keeping the same tanks to the atomizers. (other brands may not perform as well)
