Refilling "disposable" cartomizers

[xNaTe21x]

Lately I've been using the dropping method and it's working pretty well. I have a Cig2O e cigarette and I'm refilling the cartomizers. Now what's the best way to go about refilling these because just yesterday the flavor of my cinnamon juice wasn't quite right and it tasted a little burnt...could this be because I might be overfilling the cartos and maybe because I'm not letting it sit long enough after each refill?

It seems that sometimes it's hard to tell whether the carto is full, and I make sure I don't let them run completely dry.

If you think it's full, let it sit for 15 minutes to let the filler soak up the liquid evenly. If it looks pretty dry, add a few drops again until it looks soaked but not drowning. If you overfill, you'll notice gurgling when you draw and the end will be wet when you unscrew the carto. Just wipe off the battery end, blow lightly through the carto into a tissue until there's almost no gurgling, and wipe off the carto.

The burning taste would come from the coil not getting enough liquid and starting to burn the material around it. If it's a mild taste you may be able to vape past it. If it's a strong burning taste it's time to toss it. If you kill a couple while you learn it's a cheap education and we all have made those same mistakes while getting used to this stuff. Good luck!
