So, I'm getting kind of tired of dripping. It works well, but it can be a pain, especially when out of the house. I bought a couple of cheap (pre-filled) cartos and really liked them, but refilling them doesn't seem to work very well... they seem to start leaking before the filler is saturated and I get very little vapor from them. Would someone please recommend some decent refillable cartos? I'm vaping a standard ego and would like to aim for cartos at 2.0 ohm or higher. Thanks.
