Your PG/VG ratio shouldn't have anything to do with how long a carto lasts. I use the same ratio and yes, I can get a couple weeks out of a resurrector. I didn't want to quit using my vendor either but it was either that or keep buying cartos all the time or quit vaping and go back to smoking (which was NOT an option). What exactly are the juices you use and who sells them, if I may ask.
I have been down this road before. You can spend money trying to find equiptment that will work with your juice or you can find juice that will work with your equiptment. If you'll PM me your address, I'll send you some that you can use in a carto for at least a week.
Thank you for the offer, but I do not want to sacrifice the juice I really like for a better performance on a carto. I have 5 juices that I consider my core juices. It has taken me 5 months to get this list together. This is why I have no intentions of giving these up. They are:
The Vapor talk store...dulcis
bwb...honey flu
Vaperite's vr4, rou's toasted hazelnut and Madagascar vanilla.
I waited too long to find these juices...I just started my second day with one carto and one juice using the dulcis...it is still performing well...I would like to see how long this one goes. I will be very satisfied with 3 days of smooth vaping, but not 1 day.
