got the x3 coils. I think they have some quality issues, because the coil seems to last max about 5 days. Before I had triple coils for the original mesh pro and they lasted about 2 weeks avg. Will try the x2 next, because imo the x2 which came bundled with the fireluke had the same taste, but lasted twice as long.
Arrived super quick about a week to UK! These coils are banging 40w just as good as the other coils at 75w for me!
