I've been semi tracking my consumption and it seems I go through about 3-4 ml a day or slightly less.
My Kayfun on my Provari was very low this morning when I went to work. I also took a iTaste VV V3 with a Mini protank 3 about half full and 2 Halo G6 batteries and cartos.
I'm still
vaping on both the KF and the MPT 3 without adding any juice and put about 10 drops of Tribeca in one of the G6 units. The other G6 hasn't been added to.
So tomorrow I will fill the KF and the MPT 3 and do a more thorough check by measuring what I put in and then extract it when I get home.
