I have 2 V10 and for some reason every now and then they leak out of the bottom...just every once in a while.
Warmer vape than a vision.
I've got 3 of them and 3 replacement heads, so far my only issue has been when I attach the V10 to my eVic, it reads the coil at 1.9ohms instead of 2.4ohms.... it did it on all 3 V10's. I switched the heads on 2 of them to the replacement heads and it reads those at 2.2ohms.
Long post sorry:
Finally - in tune with this thread - can someone PLEASE compare performance of this NEW DV Mini Vivi Nova V9 to the previous DV Mini Vivi (that's the one I got and like). I see that the coil is higher, and you don't open the bottom to change heads - but I mostly care about any difference in the heat, flavor or draw - I see no problem with maintenance or filling on the older one...
