But I got the black one and the air flow ring as stuck wide open.I had read a review on this happening only on the black one, must be the Finnish that makes
this happen. Any way to get it to release? But that aside I will still give it a 5 star rating because I like it.

Great service...

Great tank, great flavour off it it, doesn't leak, the seals are great on them

This is by far the best Sub-ohm tank I've ever used, and I've had a lot of different tanks, from various brands.
The flavour and clouds from this tank are unreal. The coils last for such a long time (I get about 8weeks use). And I've never had a single problem with leaking. Comes as a 2ml tank obviously but you can pick up a 5ml bubble glass for a couple quid.
Can not recommend this tank enough!!

I had the misfortune of dropping my last set up and smashing the tank. Went to the Wath branch and they recommended this.

By far the best tank for flavour and cloud production that I’ve used!

Awesome bit of kit
