Got mine yesterday - though tis possibly a 'clone' as apparently the 'clones' come with a spare 3ml SS tank and the 1.2 Ohm build installed. Having broken me only KST tank (thought i'd brought a spare, but didn't fit) i'm not too disappointed with that. The flavour and vapour production are good, and the top fill is easy - just as well as i'll need to use it a lot in 3ml mode as mentioned above.
The air control, on mine anyway, seems to allow either mouth or lung hits easily, and am interested to see how long the wick lasts, as i've had issues with nasty wicks on me KST mini, which i've assumed could be down to the 'authenticity' of the 'USP' PG i bought over here. Tastes fine but wick seems to go black much quicker than the same cotton did using my BP PG bought at home.
'Clone' or not, got to say i'm very happy with the Aqua FX - thanks to

PS
Just to add - absolutely no spit back noticed - despite the vertical coil - which added to the other benefits, already noted, is definitely making this tank a Big Hit! One of the reasons the coil is tucked away in that case was to combat this - so excellent design by Footoon
