Awesome! Welcome! Be sure to get some
juice so you can top off those cartos. You should be able to get 4-7 days out of a V4L carto if you add some juice into the stuffing whenever the vapor seems light or a bit dry. If you let them go totally dry you could singe the stuffing and ruin the flavor for that carto.
My V4L juice faves so far are WOW Vanilla and WOWbacco (dark cocoa tobacco and WOWboy is the same but with a bit of mint added). And I add any compatible-flavor juice I have, not just V4L juice. Vanillas, cocoas, tobaccos - if you have those juices you can use one of them to top off almost any flavor. The flavors will blend and eventually the carto will be all the new flavor. I take the carto off the battery when I add juice. Pop the mouth cap with an unbent paperclip inserted just far enough to pop it out. Hold the carto at an angle and a tissue on the threaded end if I am adding much juice or have a juice bottle that might drip extra. Drip onto the inner metal sides so the juice slides down into the stuffing. Then I make sure the threaded end isn't leaking and is dry and clean. Then I puff into the threaded end a few time to make sure the air channel is clear. I try to keep them damp to get best life.
I also recommend their delrin drip tip - I would not drip into it - the juice would likely end up in the central air channel. But I use it if I have a hot carto. Keeps your lips cool.
