been vaping a few months, just got my 510 Boge Soft cap blank cartomizers yesterday, and am NOT loving them, I put about 10 drops in, it looked filled, I got a harsh taste and not alot ov vapor, my wife also did not get a whole lot of vapor, we switched back to the old cartridge and atomizer and it was fine. What am I doing wrong ? How many drops fills a cartomizer? Does it need to be 'broken in' ? Thanks alot
