    Good tank and very well made. Flavour is good and airflow is suprisingly airy, was going to get the Valyrian tank but the coils are twice the price of the Crown4. This came with a spare bubble glass as well as the one fitted and a straight glass plus two round wire stainless coils.

    Good tank – not quite as much flavour as the Nunchaku 2 in my opinion but more airy which I like. But it’s easy to operate, great to have the 6ml capacity, and the coils are very inexpensive compared to other brands eg Falcon. Really solid sub tank.

    This is a bargain for the sale price of £14.99! Came with a bubble glass pre installed and a spare straight glass, drip tip cap, various replacement O rings etc and a spare 0.2 coil as well as the 0.4 preinstalled. 4* for the tank, 5* for the excellent service from this site.

    + PROS: reasonably airy with airflow open large capacity coils are cheap
    - CONS: flavour could be better compared to other uwell tanks
