Did you pre-fill the carto? I pre-fill a Boge / IKV carto with a single 3/32" punch. Wicks perfectly.
I'll second that. You've go to pre-fill these. The liquid naturally likes to wick down, not up. You'll get filler taste then if the top of the cartos dry. These are Boge 3.0 ohm I bought from C.C.V. The money I make from these pretty much goes right back into the vaping community. I could buy cartos wholesale, but I choose to pay retail to help out the vendors like C.C.V. and Ikenvape.
Keep me posted everyone. Looking for lots of feedback, as I want these to be the best tanks out there.
