#4.
VVV polypro with screw. Boge standard resistance. Normally used on a cheapo 900 ego. On vapeonly now at 3.8v I've gone from 3.3 to 4.0
This tank has had pomegranate in it since I won it. Replace the carto regularly. If I go high I taste salt- I made the juice no salt just flavor and vg. No recipe changes. This is third tank out of the last one I made. Maybe it's just getting old.
4: Could be the boge carto, the batch I purchased and have read many other peoples opinions is that they are not performing well right now. People who buy many at one time find some work like they used to and some do not.
