Same here.... no real heat buildup. But I don't think there is anything that isn't going to heat up. On the ViVi, I know it's hot on dry burns, but I've seen no detriment due to over heating during vaping. Most juices discolor, but they do in every tank I've had.

As far as batteries go, I've used single 14500, dual vv on 14500, 16340, 18350, and the iTaste. I've noticed no undue battery usage. Of course, there are a lot of variables when comparing battery consumption.

Sorry the ViVi isn't working out for you, but if one thing worked for everyone, guess there would be only one on the market. Good luck finding your perfect vape!

I am wondering what the life of the heads are. I am getting a tasteless more or less vape on a pre build head. Sometimes I will get a hint of taste but most times it's pretty... blah. Happened about a week in. Not sure if I should "clean" it or just rewick it.

As far as it heating up. I have noticed that if I do a bunch of hits in a row it will get a little warm at the metal cap on top but nothing super hot or anything like that. I still get a lot of vapor, virtually no throat hit since I started (10 MG nic) which is fine because I am just looking for flavor anyways.

Maybe you are having this heat issue on a V1 nova, not that I did. Certainly not a v2. Frankly, Ive checked the tube inside the tank for heat and its cool to the touch. Room temperature in fact. The atty head gets hot, but it should be that close to the coil. The coil IS insulated on the v2.5 heads. Thats what the white wrapper is around it. Not sure what material it is.

Really, I have no idea what is making your vivi's heat up like that but mine dont. Not even my V1 does. If stone tanks work for you then keep using them. Alot of ppl swear by them.

I run my vivis on a vmax with 2.8ohm heads at 3.4-3.7v never had juice scortch yet and the vmax runs hotter than any other APV on the market with the way its PWM has been implemented.

You situation is curious.

Well I have decided after a few weeks that the nova isn't for me. I originally liked it and have written a few positive updates but there are some issues that made me go back to my vision stone v3. I think the main issue is with the design which on the surface was a good thing.

The small tube and plastic/ceramic cup in ce2 designs can be a little fragile. The nova solved this with a very robust center tube. The metal replacement heads are also very nice on the surface as well. The problem with having this much metal in the tank, and a metal coil cup results in a huge conductive surface area. This means that when you fire the coil the heat flows into the metal. Now you loose heat that normally would be vaporizing juice. Vapor picks up once the whole assembly has been heated up. Now the problem is all this heat then is transferred to the juice via a large surface area. This results in cooked juice. After a few minutes of vaping the entire tank is hot.

Now all that is not great as is. Another side effect of this is that the coil is very inefficient. loosing all that heat to the metal means that I need more voltage to get good vapor production. Which makes the heat issue even worse. For instance my v3 stone gives massive vapor at 3.3v at 2.0ohms. To get that kind of vapor from the nova I would have to run 5v at the same resistance. At the same voltage and resistance, the coils are producing the same amount of wattage but the heat is being lost to the assembly.

This results in short battery life and cooked juice. I was originally ok with the reduced performance due to no leaking, but losing half my juice to cooking in the tank made me put it away. I found out why I was having leaking issues with my stone 3 and it is the tank for me.

Conclusion: the build quality is top notch. The design looks good, but as a vaping device it is fundamentally flawed. I love that this tank was developed. It attempted to solve some issues other tanks have. In the end like most things in vaping once you fix one issue 5 more crop up. I think the biggest change I would want to see is a different cup material or an insulator between the head and the main tube to stop the buildup of heat.

when one dry burns, does this not burn the wick?

I haven't burned one yet, on anything. I imagine when I start playing around doing my own coils with cotton or bamboo thread that my dry burning days with the modded ones will be over. I will have to recoil when they get gunked up.

Thanks for the reply cleaned last night ,worked like a charm.vaping like new again . I don't think I'll go 4 tanks again tho,a lot of build up on coil.live and learn I guess.

You've got a good feel for it now and about all I can suggest is dry burning at 3v if you have a VV PV, it reduces the chance of burning the coil and give you more latitude as to how long the power bursts are.

You have to be careful not to burn/pop the coil, but the wick doesn't burn. Dry burning cleans the wick. Some folks have changed things to cotton wicks for their own use, and I think those can burn, but the wicks used in these don't to my knowledge.

did you buy the nova form us and was it the 2.5 version, is there a reason you didnt try the other head or simply the tank isnt for you?

Mine is from CoV. GV never has them in stock. CoV has V2. The flavor is weird, not nearly as good as my stone tanks. Kinda dry and muted and a bit strange like rubbery or plasticky or something. The Stone produces much more and warmer vapor. The nova does not provide me the TH that a carto or stone provides. Idk what the issue is with mine. I'd try a 2.5 but idk if it will help. I'm back to my good vaping but gurgerly stones.

ok then i truly would suggest you pick up some heads form us(at least one) to give it a try, i cant tell you what others carry, i know what we have and the results we are all getting, If you would like to give it a go and test your luck let me know, pm me and ill do something special on a head for you so you can retry the nova, I really dont want you to miss out what could be something special.

We worked hard on the vivi project and hope people know even though v1 had issues we continued forward and had them improved, some wonder if there is differences between 2.5 and the 2.0 and there is, the reviews are also gearing that way as well, try it out if you can and take it form there.

There is a video last week where someone also got what you described form that vendor and then realized it wasnt the same as what he purchased form us

Just my :2c: but I would definitely take bad up on his offer. I'm not knocking other vendors, or trying to just be a gv cheerleader, but I've seen over and over where folks got some type of juice holder from other places, and didn't like em, and the folks who got the same type from GV loved em. After awhile you just gotta figure there is something different about ones from GV.

I dunno what the problem is. I've never noticed my tank getting hot, only just slightly warm. With the 1.8 ohm head at 3.7-3.8v, I get massive amounts of vapor from this thing. If I turn up the voltage any higher, it produces a bit more vapor but the juice I'm using starts to scorch. I'm not sure what version you have, but I have never ever had to step up to 5v on my v2.5, even with the 2.8 ohm head.

that applies to many products yes debadoo but i also dont want to mislead anyone either, we also get products that are exactly the same as other vednors and vice versa, sometimes its just the TIME of arrival of when who gets what that seperates any improvements, sometimes other have improvements first, sometimes we do, many times we work on products and have them improved and so on and we always look for the latest products and work with the factories closely. We have noticed the same thing where people have also said there sometimes is differences in what we have versus elsewhere, this was noticed on the vivi, on our vision extreme line, we where always a step ahead on that, our ce2 fluxomizer line form microcig and our phoenix line and our sapphire line etc..

By the way we have some huge huge news regarding the phoenixs which i will get into in a few days.

So buying a 1.8 head from you guys will be fine on the v2 I have from CoV?
