This combo works well anytime I need it. I use it on my eGo when away from home or desk and on my VAMO ( at 7watts) at home or desk. Good flavor with no leakage. One carto lasted me a full month. Only one issue with the carto, if it is left on its side for too long it floods. Not that big of a deal. Just upright it, wait a minute or two, and I am ready for vaping.
