OK, in quick summary:
v1 ViVi was, and is, usable in most cases. On the ones that work as intended (most of them), the consensus was/is that the flavor is a tad more muted than people like. On some of the heads, however, there were problems: some tasted bad (burnt oil or such), and some gave no flavor whatsoever.
The v1 tank is usable with v2.5 heads, the stem in the v1 is a little shorter, so you get vapor in the tanks, and i wouldn't tilt or fill it to where the juice gets in there, otherwise it works great, no prob. Using it now.
If you want to try your v1 heads, wash them really, really well - apparently the occasional bad taste is, pretty much, from oil. Then try them. If they work, they work. If not, you got a good working tank for the new heads.
I did nothing to the new version but vape it, and it vapes very well. I cut the wicks down on another v2.5 head, and it workes even better - the flavor got stronger. YMMV. But no modding necessary, IMHO.
Oh, I'm sorry, I lost that message, but someone wanted me to post a pic of how far I cut the wicks - sorry, folks, my camera went a bit cablui. Basically, it is just a tad longer than to the walls of the tube.
HI people

, I am wondering if somebody would be able to kind of sum-up what was wrong with the first Viva Nova. I bought 2 of the first verstion when they first came out, but I had also bought some 1.5 and 3ml Phoenex's also. I have been so busy with and using the phoenix carto's that I never even opened either one of them. I also knew that people were having problems with these and that is really the main reason I was waiting to try them. Well I pretty much will always take the time to read thru the threads on items I purchases so I will know how to mod or what ever. I just put another order in and I ordered one of the new nova's, and some extra atty heads for it.
So I am just wondering if someone could tell me a little about them, like are the first version even usable? If not can I use some of the parts of it with the new version? And do Ineed to mod the new version at all? I am going to try to read some of this thread but would really appreciate if someone could help me out. Thank's and sorry for the book I just wrote lol
