That's pretty much all I wanted to ask. I got some 40/60 PG/VG juices, not realizing that was not the optimum ratio for the Go-go cartos. The one I've tried so far is working okay, but would it work better if I thinned it a little bit? I only got small trial sizes, so it's not really worth going through a lot of trouble to adjust them, but if adding a couple of drops of water would work, that would be great.
