Any time Ive used V4L juices they have been in the V4L cartos. But recently I haven't been using cartos very much because I just love the feel of my 510 and 801. So I was looking into buying just the juice and using the juice on my 510... I know people have done this / do this but I was wondering how well the flavors and vapors do in something other than a cartos. Im also looking into cutting the juices with some VG because PG has just been rough on my throat lately with horrible weather in my area right now. I got a pack of WoWBoy about a week ago and the flavor is just delicious and I was going to buy a bottle to try it out on my atomizers. But didn't want to waste any money if there was a drastic difference in flavor or anything like that. I deal with many different e-cig models and such every time I work at the vapor shop and know that different attys work better with different juices
