Honestly the battery rocks and $10 for 5 new carts isnt bad in my opinion. Vapor production and throat hit is way better than njoy's express kit.
I have noticed that the threading is the same as NLA (never light again) and I can use NLA carts with my FIN, however I cannot use FIN carts with NLA (doesnt fully connect!) anyway, I really want to know if this is a 510 model because I really want to try a cleanable, refillable Mega XXL with this unit.
I have been refilling my carts just by adding a couple drops to the top hole. Seems to work just fine.
