I hope this is in the right section....I wouldn't want to get another INFRACTION. But I've been filling my cartos this way and I thought I'd share it. I don't know if anyone has done this but nevertheless, here it is. I've seen the condom filling method and the tarry spin. I kinda do it both at the same time. I take the condom with the plug in it and put it all the way on the battery end....real tight so no juice can leak out. I made a spinner out of a chapstick tube. Poked two holes in it and put in a skinny shoelace. Put the carto in that and fill it till the juice is just below the top. Then spin it. Do this a couple of times and you have a juice packed carto. Blow out the excess and vape. No waiting for the juice to flow...it's great right off the bat. I tried this with a 2.5 ml carto and did not have any dry hits at all. You know when it's full when after you do the last spin the filler is real wet. Hope this helps.
