Mine arrived today. I got the menu system down but the atty just keeps running dry, my juice is mixed at 80/20 PG/VG which is already way more PG than I like using. I tried blowing, taking the cap off (which desperately needs knurling) etc, it'll feed for a little while then stop again. Over all it's a disappointment and will be delegated to a draw and only brought out to test new flavors by dripping, the JD imho isn't worth the trouble. Guess I'll just go back to my UFS on my GGTS at least that always works perfectly even if it's not vv beyond changing the battery/atty combo.
