Have followed your posts in regards to your trials and tribulations and methods with the Greencig refill. If you think you've messed up some carts!! lol- Anyways, do you still find dripping the battery end the easiest way to go. I have not had much luck taking cart out, cutting off top and dripping nor with either syringe method i've tried. Whenever i get it right it's awesome but very inconsistent. It's probably due to the fact that i wasn't born with a mechanical bone in my body!
