i have an ego-t and i refill my cartridges with juice.....question: i have watched alot of videos where they pull off the little rubber stopper on the bottom and refill it that way....hmmm i just inject juice through the little hole at the bottom with out pulling the stopper of?! so is that the wrong way to do it? also i have seen them refill through the mouthpiece but i tried that and couldnt find the hole lol...(the blue mouth pice)...i even tried to fill it by pulling the rubber stopper off but had juice all over and a hard time putting it back on......so what is the right way and less messy one lol
thanks....
thanks....
