Greatly improves the draw if your into a tighter MTL draw.
A perfect addition from Geoff Edwards on 10/12/2020
As previous reviews have stated if you are a true mtl vaper this is a no brainer, it takes the guess work out of adjusting the airflow pin and provides a tight mtl draw to perfection in my opinion, the only reason I haven't given this 5 stars is that for the price of the atty I would expect this included! Absolute first class service from CdV again and would recommend them to anyone without hesitation
A must have for the mtl vaper from Christer Sandberg on 01/10/2020
A must have if you are a mtl vaper. Imho, the KFL19 works good either way, but this center pin fixas that draw and makes it much more tighter and the nylon screws are also longer than those you got with the first batch KFL19
