awf, what blend of juice are you using with the fluxomizer? Same for the sapphire? Please tell me its all PG or I'll be jealous. I can never get fillerless cartos to wick and vape well with any amount of VG, they just burn, with a few exceptions, and 100% PG juice always working fine. I think my 70/30 pg/vg blend may just be thicker than most for some reason.

I'm glad yours are working so well though lol
