hi all, I'm wondering how long your coils last on your mini vivi novas? I know this is dependent on usage and other things but just wondering. I switch between the mvvn and t2 often and both are sharing the load of use 50/50. My mvvn is over a month old, used daily and still on my first coil. I clean the coil probably once a week or so and have only done one dry burn which was a few days ago. The dry burn took awhile as it was pretty dirty. vaping like a champ again. not sure when this coil will pooch.
