Thats awesome, I am glad it works for you as well. If it is common knowledge I was never able to find it. I found tons of posts saying that it was from overfilling, or tips on blowing the cartos out one side or another. It always still did it for me. I figured it was my fault cause I like keeping my cartos real wet. I think they last longer, I had one for more then a month. My only problem was that the drip tips worked great on the cartomizers when I am home. However on the road, I would have to give up one of my carto spots in my travel case. The slots aren't long enough to allow for the carto and tip. Plus that would be leaving cartomizers sitting in my case without a plug in them. After a little experimenting since my last post I think I discovered another effective way of preventing splashing without a drip tip. Although realize I am still testing it out.
Take one of your cheap plastic condoms for the cartomizers and cut out a large hole in the bottom. It should be around the same size opening as the drip tips. Now after filling the carto, place the regular tiny holed plug in the carto, then place the rubber on top of that. Don't push the rubber all the way down onto the carto, about halfway. Then vape on that. It should produce the same effect, albeit not as well as the drip tips. But you can just push the rubber down fully on the carto and place inside the traveling cases and you are set to roll, just pulling it halfway off when you want to vape. So far it seems to be working, I filled one up so far it was clearly too much, dripping horribly out of the battery end. I cleaned it off, put the plug on and the rubber on top. I vaped on it a ton and after awhile I could see through the rubber that the plug had allowed juice to gather on top of it. There was even some juice from condensation on the lip of the rubber. But it was inside the rubber, not on top. It is not as easy to refill as the drip tip, plus it doesn't prevent the splash's they are still there inside the rubber so you would have to clean them, but at least they aren't in my mouth or lips. I need to do more testing, but I think I have found my new travel case solution.
I think I am also going to try and see if drilling the hole larger in the plugs could solve it also. But not sure how I am gonna drill this tiny piece of rubber without drilling holes through my fingers..
