The e-cig carts operate by releasing vapor into the stream of heated air flowing over the juice filled wadding.
In order to improve the efficiency of this process you can cut a small triangle out of the top ridge of the cartridge.
(a small pair of nail scissors are good for this mod).
Unmodified classic cartridge.
This mod really improves the vapor production.
Modified classic cartridge.
This increases the area of the boundary between the airflow and the stored juice, and therefore significantly improves vapor production.
Please let me know how much improvement you get......
