As per previous review, this revised version work fine with the updated inserts. Very good flavour, easy to build on - absolutely no complaints.
Don't be put off by the negative reviews online, this is the revised edition and the airflow plugs fit nice and snug.
I can't fault this little mtl tank, to be fair it has the best flavour of any mtl tank I have ever used. A little mtl tricore Clapton coil at 0.7ohms is what I am using.
Definitely worth buying, nicely made good looking tiny tank.
