I just received my latest shipment of juice and went for VG juice this go around. I was very excited since I have party this weekend and it arrived just in time. Put a new carto in my tank since my old one was burnt out and filled the tank with Vanilla VG juice. It seems to only pull vape with a fully charged battery and even then has very little flavor. What's the deal? Am I missing something? Doing something wrong? Thanks!
