Must have for proper MTL from David Ferguson on 30/12/2019
Tightening down the original air flow pin for a tighter draw creates an annoying whistle, although it's ok when wide open. This pin allows for a tighter draw without the whistle. Recommended for 'the tighter' man.
Does exactly what it's supposed to from Anonymous on 22/11/2019
If you find the draw stock pin a little to loose, look no further! Easy to install and works like a charm.
A must have for a KFL19 owner from Mateusz Sobkowiak on 21/11/2019
The xs centre pin for the KFL19 completely transforms the vape quality, getting rid of any whistles and turbulence in airflow encountered with the stock centre pin. It's a no-brainer especially at this price. Don't hesitate, just do it, you won't regret it.
