These Quad Core FC are fantastic. I rarely vape Ni80 and usually go with SS or KA1, because I'm not as keen on the taste, but these are different.
The flavour is outstanding and they're very nicely wrapped. I can't speak for longevity, but as with all coils, if you look after them, they'll last. Came out at 0.16 with 6.5mm legs on a dual build, which is higher than the estimate but well within reasonable tolerances.
Running on the VC Trilogy with Firebolt cotton, these guys kick flavour and clouds at 100w.
For the price per coil, these beat any competitors coils that I've tried.
Really nice coils, came out at exactly .15 as it was supposed to. Will certainly buy these again
