Talked to Jay and was reassured that it was most likely the atty's. Of course, Jay was completely wrong. He apparently didn't take into account operator error or was just trying to be nice. I normally fill multiple cartomizer's at one time so that I don't have to fuss with them. I think what happened was in my haste to try my GLV-2, I just filled some new carts and I wasn't allowing the wicks to saturate and was hitting dry. Either that or as Jay said I may just have found the bad atty's in the bunch.
All fixed it seems and since no one else has mentioned this anywhere, the GLV-2 is a great mod.
