I don't sub0hm so take that for what it's worth, but folks seem pretty consistently happy with the Uwell Crown (original or 3, 2 not so much) and coil life tends to be longer by most reports I've seen.
@AshKicker , you are the new expert on "what" coils go in "which" smok devices, it's great info I think, so thanks for compiling those lists. To the OP, I think if you like the tank other than coil life, trying some non-proprietary coils
may help, and cost less. Do keep in mind that dark, sweet, or otherwise gunky juices (like NETs or WTA) may lessen coil life across the board, although some coils can handle more "gunk" than others and keep on going.
