Pros:
The secret of this tank is the constant wetting of the cotton from the top, right next to the coil, which leads to very consistent flavor and throat hit, even while chain-
vaping.
If the cotton is placed correctly (over the screws) it won't leak - ever. Also due to side airflow.
Very easy to fill and maintain due to simple construction.
Huge juice capacity, whole day for me (6-7 ml). dD variant is 19 ml!
Very sturdy.
Cons:
Won't win any beauty contests - tall piece of metal which is not pocket-friendly on any mod, except on a side-by-side.
Overall:
Simple design, excellent
vaping.
