Yeah, it would have to be someone huge to have the right equipment, and there would be QC issues at the wazoo, and pyrex isn't like metals or plastics where you can do some sanding and working yourself. You would be stuck with it.

Got my Vivi Nova tanks (2) in today. First one with 2.4 head is tasting near perfect. Not full flavor but pretty good. Havnt tried all the heads in that set. My other set, both the 2.4 and 1.8 ohm heads glow bright orange below the coil, taste is weak, with slight burning. But tons of vapor out of all the heads iv tried. I have some wick and wire coming in the mail from COV so hoping the rebuild will greatly improve my experience. So far still much preferring my Boge LR carto tanks.
Well, I don't about you guys but I got my Vivi Nova over the weekend and I am extremely happy with it. From the first fill I got great flavor, clouds of vapor, nice throat hit.. no dry hits, no burnt ickiness... and I've only used the head that came assembled on it.. haven't even touched the other two yet. I have to say that I'm a total noob,, I get confused with the ohms and the amps and the volts and all that,, I just know what I like and what tastes good to me and this Vivi (so far) is awesome on my lavatube. I've spent way more on cartos that burn after the first fill or are dead out of the box.. this thing is fabulous!
Got my Nova on saturday and started out with the 2.8 head on the good ol provari. Did not mod it at all to start with. Wanted to see how it was out of box.
First, the provari reads 2.6-2.8. Started out at 4.4 volts. First few vapes were great. Flavor was there. Now i did not get a nasty burnt taste but i did get some burning feel at the back of my throat as if it was drying out. This was happening quite often. I decided to start small and just remove the loose wick on the top. That seemed to fix it and no burning. So far im impressed with the nova. Cant wait to see future improvements on this

I just received my first Vivi unit. After reading most of this thread I have a couple questions.
Is it a good idea to screw the head units directly onto a battery, put the drop of juice on the coils and make sure the coils heat up correctly?
If just the wire lead heats up but not the coils can this be called DOA?

That's what Id do if I were you. drop a few drops of juice on the coil first.
Been vaping the 1.8 head for the last 5 hours now. Its working better and better. Still have the glowing wire under the coil, but so far no burning taste on this one anymore. So I'd call this one usable. I will definitely rebuild the 2.4 and 2.8 coils when my wire and wick come in the mail. The 2.4 is not usable for me, not even going to bother with the 2.8 as I'm confident I will enjoy it more with new wire and wick. I hope future revisions will include non resistant leads near the rubber(ish) seal on the connector to prevent any burning that i see people reporting on this thread.
I forgot to mention, I trimmed the wick on the 1.8 head. Left the very bottom wick long, and cut the top 2 short, as well as removed the top loose wick. The flavor has improved greatly, still not as good as a boge carto in a tank. But again, for an easy cheap rebuildable head and tank system, its pretty good.
For what its worth, I gutted an old carto and removed the bottom seal from it and replaced the one on the ViVi head with that. It was a grey color, not brown and so far it seems to be holding up a lot better.
I only got about 3 hits from the original one before the "burnt rubber" was covering up any other flavor I would have had.
What brand of carto did you use, and can you post pictures by chance? I was wondering if there was something I could use to replace any possible burnt seals so I wont have to keep buying new heads, and just rebuild using what I have on hand.
It was a V4L 808 carto brand new as I don't even have 808 stuff anymore. I can post pictures later. I've been vaping it all day to see after diss-assembly how it looks compared to the "original" rubber. I can say for sure there is a difference because I got the nasty taste QUICK on the stock on. So far so good on this one.
P.S., the seal was the EXACT same, just different color. Maybe different material altogether???

Got my Nova tanks in today and so far so good on the 1.8 head. Great flavor, tons of vapor and seems to be wicking very well. Only modding I did was covered one of the air holes to tighten the draw.
Just got mine today. Indeed a very airy draw and muted flavor so far. Still trying the 2.4 head that came on it, hoping it gets broken in soon.
I took a paper clip and bent it so I could get one end in each hole. It doesn't block the holes completely but it helps a lot. I just pull one end in or out further for adjustment as needed. Gotta be careful not to let it hit the center post though.

OK, Here is the picture of the Stock Grommet on the Right and the carto grommetView attachment 98660 on the left. The original grommet was NOT fired at ALL by me. The little mark seen in the photo was from the FACTORY TEST FIRE ONLY. If the test fire does that, imagine what actually using it does.
I have not disassembled the one I made this morning using the carto grommet to see if it held up any better. The one pictured is a new one I just used on another head.
Getting ready to tear apart the one I've been using all day and will post pictures of the burn if there is any. Thanks

Okay folks. MY verdict is in. Now I'm no scientist, just a DIY goofer offer. But I can say for almost certainty that the two grommets are made from a different material. Why they did not just use a carto grommet in the first place I have no Idea.
First photo is just the head I made this morning and vaped all day. The second shows the carto grommet with NO burns what-so-ever. Not even a dark spot. There is a slight indentation in the grommet from where the wire was pushing.

I was using .16 nicrome wire. I made one up tonight with .20 kanthal wire. Will see the differences after I use that.
Also, this morning used my own fiberglass wick. Tonight I re-used the supplied wick (without the dumb-... wick over the coil). Just trying to figure out all the reasons why so many (myself included) have had issues with the first run of these.

Well, I tried out three more ViVis today. I was as thorough as I could be, but not as thorough as I wanted to be. Turns out I am not a very "serious" vaper. I could not, and I mean absolutely *could not* get two full tanks down my lungs. Right now, after vaping one down to .2ml (almost empty by *my* habits) from 2.8ml, and only getting the second one down from 2.8 to 1.8 (thereabouts), I'm done. Just stick a fork in me. My head is spinning (I only vape 12 mg), my tongue, mouth and throat are tingling, and I can't taste a thing. Oh, and I can't stop twitching. 
I tested all nine heads by firing them just until they lit up (dry - no juice), and by measuring the resistance. All nine fired normally: meaning that the coils lit up simultaneously with the leads. Yes, the leads did light up.
The resistance on *all* of them measured higher than indicated on the coils. Sometimes by as little as .2 Ohms (within tolerance, I'd imagine), but occasionally by as much as .6.
All-in-all, all nine coils seemed perfectly usable at this point.
Then I filled up two tanks to the 2.8 ml line. One had GV's Caramel Apple (70/30 PG/VG) - absolutely delicious juice, btw, could easily be my all day vape, and pretty full taste, I'd certainly not want any extra flavor on that one. The other got an 100% VG juice with a fairly subtle flavor - not as thick as Boba's, but pretty close.
The heads I had in there both read 3 Ohm.
The first one, Caramel Apple, was the one I sucked down to the low point. *There were no dry hits*. Not one. Not even close. I tried voltages from 3.3 to 5.0. I didn't go any further because, to me, at 5V the juice no longer tasted right. As a side-note: I don't like hot vapor, I think it ickifies the juice, except for, maybe, some tobaccos. *And* I chain vaped. I chain-vaped so much I accomplished something I've never been able to do before: The Provari heated up to the point where I had to put it down before it started giving me error codes. The only time I put down a PV today.
The second tank, with VG, I only vaped down a bit. No dry hits on that one either, but, to be scrupulously honest, it's a little hard to tell yet. Just from knowing this juice and having some feel for wicking quality from vapor production and relative taste and such, I'd imagine I might have to work at it a bit on the bottom quarter of the tank - but maybe not. I'll update when I get down there. The day after tomorrow, probably. LOL Anyway, that one I had on 4 V to 3.7 V, mostly. It still wicked on higher voltage (I think I tried up to 4.5), but I didn't want to contaminate the tank with burnt juice.
The vapor, for both tanks, was phenomenal. What amazed me, frankly, is that both tanks worked well even at 3.3 V - at 3 Ohm resistance! Sure, there wasn't as much vapor, but it wasn't shabby, either, and the flavor was there.
There was no burnt, or rubber, or any other funkiness in the taste. None. The flavor was very good indeed. Somewhat different from the Stardusts. The ViVi had more high notes and less low notes - in other words the flavor was a bit "sharper" than the Stardust - but that's neither good nor bad, just different, to be expected in two different configurations.
Flavor strength was good. Not spectacularly strong, but entirely satisfying. What I would expect from a good CE2 type. To me, Stardust has stonger taste, but you know these things are very subjective. With the strong tasting PG/VG liquid the flavor was plenty strong enough - even I, with pretty weak taste buds, was satisfied. With the subtle tasting VG liquid the flavor was OK - but that one really only tastes strong enough for me while dripping. But I tasted it and tasted all the nuances of the flavor (which, with that liquid, changes dramatically with different power) - that's a considerable achievement. I almost gave up with it on *any* CE2-ish carto, including the Stardust (which doesn't wick it worth a poop, btw, while the ViVi does).
Before I forget: I didn't mod these things *at all*. All I did was take that free-floating thread of wick out. Just because the concept bothered me.
Sooooo... I now have 4 ViVis. Basically, I got a chance to do what I wanted to do: test a few of these guys. Out of 12 heads that I got, one turned out funky/unsalvageable, one funky-ish/kinda working, one I lost (all three of these from the first package I got), and the other nine are perfectly fine - great, in fact. I'll be buying more heads when the time comes. The odds are very good that they'll work well - even not taking the current adjustments being made into account, which adjustments should eliminate this problem altogether, I hope.
All four of the tanks are physically great. No blemishes. No leaks (yes, I tested - with water). All heads fit perfectly into all sockets. My own drip tips fit nicely into the top hole. There is a teeeeeeeeeny gap between the tube and the bottom and top lids on all of them - I'm not sure if it's supposed to be that way or not, but you almost have to look for it with a microscope, and it certainly does not effect the integrity of the tanks.
I know some folks reported that the tanks wobbled on some PVs... I didn't have that problem with any of mine, they all seated firmly. I do wish they'd go all the way down on the Provari though, just for aesthetic reasons, but they still look like they belong there - verrrrry pretty, especially with a stainless drip tip.
And as for sturdiness of the tanks... I dropped the first one and my dog chewed on it a bit (empty, thank God) - some scratches, but it works fine. Today I dropped another one three times in a row (ok, I'm a kluts - I think I'd mentioned that before) - no effect.
I think this thing is amazing - especially considering all the cool stuff that can be done with it. I'm very pleased with it, and can't wait for more accessories to come out.
So, the bottom line, for me, is this - keeping in mind that this is my personal opinion, of course, and my personal experience: if you are reading this thread and don't have a ViVi yet, and are a bit spooked by some folks reporting problems, originally, don't be. It seems to me that the majority of these puppies are perfectly fine and work great. And it's a great vape and a cool modular (!!!) tank.
Just a quick P.S.: with the two tank-fulls I tested today, there was practically no break-in period that I noticed. Maybe five puffs or so, and that's it.

Oh Briar how I wish I had your luck. I had just the opposite with mine. Though I can mod, re-wick mine, I actually bought this for the wife because I am trying to get here to "rebuildable status" and figured this would be a good first step. I never even mentioned they were for her because If I had of given this to her It woulda been over. They tasted absolutely awful.
This is in my opinion just the "first run blues" that so many of use have had. Only it seems we have them over and over again. For once I would like to get a new toy and it actually work
Again, I am glad yours and others have worked as good or better then expected. Maybe I am the minority? But mine were not worth the money spent.

While the 1.8 ohm head was/is producing a burned taste ( coil doesn't fire, wires below just glow ).... the other two heads work great and produce a good amount of vapor and flavor. I don't currently have any juices that would cause cracks or crazing of the clear tube ( and wouldn't use them in this if I had )...
Overall... the Vivi is working just fine for me discounting the one coil that doesn't. Having a rebuildable heads also intrigue me a bit... even though I don't currently have any supplies to do that. I'm curious what the new heads will have changed... I suspect it will be mostly a QC upgrade to the assembly. The future on these is certainly something to watch.
