I pretty much only buy my liquid from BWB now, going on 7 to 8 months. Recently, the bottle tips have changed and the newer ones have a much larger hole that liquid just flows out of. It makes much harder to fill or top off a cartomizer from the stock bottle. I wasn't prepared for it and had juice all over my hand and table. It made a huge a mess. Just letting you know, I'm not sure if you are aware of it or if it's buy choice or just a change from the supplier. Thanks!
