I've got 3 vivi nova 2.5 tanks, or clearomizers which ever it's called. Question is I've been using the 2.4ohm heads on my eGo twist between 3.6 and 4.0 volts. Also use them on my kGo which as I understand it is 3.6 volts. I'd like to find some place online to buy the replacement heads. Any suggestions. I've found tons of them for the Vision stardust that I use but am having trouble finding the ones for the vivi nova. From what I've read I don't want to waste money buying the one for the wrong version. I've got the newer version of them. (I hope).
