I got my kr808d-1 cartomizers and adapter for my 510 yesterday but didn't have a syringe for filling. I went online today and found out how to fill without syringe and went through the procedure. The e-liquid I got with it was vg and very thick which also concerned me but in the refilling video I watched he also had thick liquid which made me very happy. The difference in vaping is phenominal. I can't believe how much more vapor and flavor I get. I'm so exited and pleased I can't understand why joye 510 didn't do it this way in the first place. It's GREAT!
