thats a difficult one to answer as im using rafale coils which i find last longer than the crown 2 coils.
ive also got 23 mods on the go with a different flavor in each so can go through a day without touching certain flavors. i also swap the lychee and grape between se1 and nrg tank.
im guessing a week is a round about time but that week of use could take a month to get through if you get what i mean.
i also dont build so cant compare between the two.
