Just thought I would chime in with my experience so far, been vaping for 3+ days now using a ego-t, finally got my sample e-juices and cartos's (boge 2.0), and drip tip. Still trying to figure the best way to sample some of the juices, for now I just been doing a quick wash of the atty and using a cleaned out tank and it seems to be working. also have one ego hooked up with the carto and been vaping sweet tobacco and liking it, just initially used a needle fill, but now just dripping to refill. I have not had any leaking issues, mainly I think because of reading info here on ECF for the things to do to avoid. down to 2-3 analogs aday from 15+, getting the wife interested (as she sits on the couch vaping some 555.5 with a cold one, lol) Will give a follow up in a few days
