Thanks all for your help--I've realized Im quite an idiot...I actually was looking at Ego Mega blank cartirdges I ordered and thought they were the Cartomizers. (I really wish they would label everything when they send it) I can't even use the mega blank cartriges--oh well lesson learned!! I watched the video to refill the carto's..it doesn't have the screw in end on that, does it? I cant refill that way with the gold screw in end, can I? Also, how do you get the white end plug out? I'm sure these are all new dumb questions..but oh well!!
just saying....
