When it comes to the Condom Method for filling Cartos all I can say is
don't do it. This method spread like wild fire around Youtube and surprisingly enough even ends up on some suppliers websites. No matter who the KR808 Carto supplier is, all standard KR prefilled Cartos leave the factory with 1 ml of juice.
Refilling should not require the need of tissues, washing hands, washing out condoms, wiping out Carto threads and housings, cleaning off counter tops, blowing out air tubes, burning half-filled cartos, blackened battery threads, clogged air intake holes, killing auto batteries, or accepting that a few drops will have to be sacrificed on every fill.
Here is a classic video of the Condom Method most new Vapors stumble upon. This is just one of 100's, when viewing these vids note that if they don't cut-away after filling you'll see them wipe down the carto or need to blow out the Cartos.
