Bought two of these fellas. The flavour is amongst the best I’ve had from a tank especially being a single coil. However, they both leak badly, from top cap orings, bottom orings allowing liquid to seep down outside tank and through airflow due to the insulator which doubles as a oring to seal the positive pin on the deck. Just be prepared you can have a good one or if your unlucky like me, pick up some leakers. A real shame.
