Yeah I know the black flames are painted on and will wear off eventually and some won't like them but I think they are pretty cool.
I don't have an authentic to compare but I get 18W sustained on a DNA40 set to 410F through chain vapes using 100%VG with a couple mods. I did drill the air stem/positive post on this to 2.5mm and the 4 side inlet air holes to 2mm each. Performs better than my KF V4 even with its'
juice channels drilled out to 1.6mm. I find I am grabbing this and the Lemo quite often. Though the mammoth wolverine is getting hard to put down too LOL.
And no leaks. I did trim the wick closer to the grooves than shown in that picture above.
