I recently purchased the tank only (not the complete kit) because I wanted one with a stainless steel enclosure for durability/protection. The built-in airflow control is an added bonus which works well. After three weeks of daily use, the tank performs great. However, the primary reason I'm posting this review is because I want to mention that I've had to add a 510/eGo adapter onto the tank in order for it to work on any of my mods (Innokin iTaste MVP2, Innokin iTaste VV 3.0, EVOD Twist VV, e-Go-C Twist) because it seems the eGo base on the tank is slightly too long when screwed onto any of my mods and prevents the coil from making a connection with the battery pin. I don't think the base on the tank is defective/irregular or not-made-to-spec, and I've tried the original stock dual coil out of the box as well as a rebuilt single coil, but I've had no other issues using any of my other Kanger/Innokin/Kayfun tanks on any of my mods - so I just wanted to post this review and mention this so that others can comment on their experience with this tank when used with a mod other than the one included in the kit.
