I've seen this methond used on cartos with a 808 battery connections but have never seen a 510 carto to demonstrate this method. Any thoughts???
Yes, it does work. If you are using cartos that have the soft white removeable cap just make sure you do it slowly or you'll squirt juice out of the mouth-end of the carto.
NO I do not fill my 808 cartos from the battery end, I fill them from the mouthpiece end! I am assuming the same would be done with the 510 cartos..
Is the condom cap method different than the condom filling method? I use condoms to fill my cartos and would never fill from the battery end because I don't want to ruin my batteries.......
