I've been using the X1 coils in my Fireluke 3 tank for over a year now, and I'm more than impressed!!!
Using the tank on my trusty Aegis mini 100, they give amazing clouds, great taste from my juice and surprisingly last up to 2 weeks. Which is pretty damn good considering I'm a dessert aficionado & particularly love my sweet vanilla based juices, which are well known coil killers.
I'd recommend these bad boys for anyone that is serious about the getting the great cloud production outta their sweet juices without having to change coils every 2nd day.
Cheers 🤙

Great Product
