You're certainly welcome. I love this unit. I think I'm going to become a BMF evangelist.
I need to clarify something, though. I had stated in my post that I was using Vaperite Organic Tobacco (a 50/50 PG/VG blend) on these cartos without issues. Today I discovered that when a carto is completely dry of its original PG filling, the 50/50 Vaperite doesn't vape very well. I guess dripping into the not-quite-depleted cartos with the Vaperite, I was getting a good ratio; now that I have one that's about dry, after dripping it with the 50/50 I realize it doesn't work well. I don't get a burnt taste, but the vapor is minimal and the TH non-existent. Lesson learned: 50/50 is not good on these cartos. I can cut the juice with PG to make it work, so no loss, but I thought I should make that clarification.
