I'm not necessarily blown away with the nKFL. But have taken a liking to them enough to now have 2x 22mm and 2x 24mm nKFLs. All setup with the long mode tank. So I suppose you could say I like them well enough!
The 24's are on Dani Mini's and the 22's are on JAC's.
It did take quite awhile with the 1st one to find a build that I liked. I was almost at the point of selling off the 1st one actually. Then I dropped down to 30g Kanthal from my usual 29g. And also from a 2.5mm diameter coil to a 2mm diameter to allow as much air flow around the coil as I could. Geez, I hadn't made a 2mm coil since the days of rebuilding clears's and Vivi Novas.
I also use a wider bore drip tip, either a K5 tip or even a V3 mini tip (which maintains the look of the original. Another tip I like with it, is the black tip from a Zenith tank. It's low profile but has the wider bore.
