He is slightly narrower than normal round battery and its socket and Driptip quite long. Füllhöhenbedingt, the tank is unfortunately always empty when he actually is. But it can get used to, as usual for almost all tanks.
Handling is good airflow through the 3 small holes also very sufficient. The taste and also Leistungstechnisch me has surprised the mini 3-powered Dual Coils PROTANK. Very balanced and powerful for its size. But as I said, it is too narrow for normal batteries. Besides, you want them to have so.
Addendum: The cap, which receives the fireplace and holds the glass in place is a bit on manufacture processed "wrong" and thus the whole tank sits slightly schränger on the battery carrier. This is only one millimeter at the top, but one can bring to the mind. -1 Star
Since the fireplace is quite wide, you can just little fill and must repeat the procedure several times a day.
