Well Just got done with mine, Made it out of a 10ml Syringe, Two American Standard Stem Repair Aqua Seal Washers, and a Smok 2.5 ohm Mega Carto - Washers have two O-rings, and the seal is Seriously Tight, no air Leaks, Looks Just Like a Liquinator. Even tho It's Not A Liquinator, it has the same problems as one, it tends to leak from the Battery Connection end of the carto, but not the tank at all... Been Looking on U tube and other places to see if there's a fix other than trying to push the carto down to close off the holes, but haven't found anything, I was trying to see if you guys may have some suggestions on it, cuz the carto just continues to over fill, and it's drivin me crazy
Before anyone asks what kind of holes or slots there are... There are two Small Drilled holes right where they should be on the lower end of the carto, right above the bottom Tank seal

Thanks Guys!
