I have been using novas pretty much exclusively for almost a year now. I use both the reg size and the minis, and I find that the mini are designed much better. A lot of the problems that I have with the novas, I don't have on the minis. BUT I don't like the minis because they are mini! I don't like refilling all the time. So I much prefer the full sized novas... which brings me to my problems with the full sized novas:

I just haven't found anything that can compare, let alone improve upon the novas as far as flavor/taste (when the flavor is consistent) and performance/vapor production. I do have my complaints though.... They are definitely fiddily! For a while I was having a HUGE issue with that damn rubber cap. It was always getting twisted, or pushed over too far when screwing the novas cap back on. Which obviously would result in leaking/gurgling. Since then, I have found a work-around for keeping the rubber cap in place while screwing the top back on so that is longer my main issue.

My MAIN issue with the novas is getting constant juice flow into the coils, so that the flavor/taste is consistent, EVEN when chain vaping. What happens a lot when you "chain vape" the novas, you lose flavor, and get a burnt/bad taste. ESPECIALLY with thick, VG juice like bobas. Simply tipping it doesn't help. So, the only solution I found is to cut little nitches in the rubber cap, where the wicks come out. Problem with doing this is that it is a BIG pain in the .... PLUS you have to be veryyyyy careful how small you cut the nitches, because if you cut them too big, then the nova will flood and gurgle. And then, once you cut your nitches, lining them up perfectly with the wicks while screwing the cap on is ANOTHER challenge.

My final complaint with the novas, is leaking along the threads. Now, USUALLY this is not a problem with the plastic tubes. They seem to make a good seal and not leak. However, I have a lot of juices that are not compatible with plastic tanks because they instantly crack them. SO, I got myself some metal tanks. These are very hit/miss. I have two metal tanks that leak from both the top and bottom threads. NOT COOL. I have ONE metal tank that does not leak, but Im afraid to buy more because i already have two that are useless because they leak! So THEN, I got the nova tubes that have the metal cover with the window. I think they call them NOva STV's? ANYWAYS, I did not have a good experience with these either, which was surprising because they are just the regular plastic tube, with a extremely thin metal cover over it with the window. But yes, this one also leaks. Leaked the first time I used it, so I emptied it and turned it around because I thought I may have mixed up the top and bottom. Which is VERY easy to do if their is a top and bottom? But it didn't matter, It still leaked both ways. So I also gave up on these nova stv's or whatever they are called.

Does anyone have any advice?? or tips? or fixes? or can recommend something similar to the nova that does NOT have these problems?? I wanted to try the T3, but I have heard bad things already with burnt taste and gurgling and that is what I want to avoid!!

UGH....SO as you can see, As much as I love the nova, when it is working well, the novas can also be a big pain... its a love hate relationship.

Tape around the seals? Wouldn't that make it very inconvenient for changing juice, heads, cleaning,etc... ? Removing tape Everytime you want to refill...

Teflon tape goes around the inner threads and doesn't have to be removed every time it's unscrewed. I've yet to have leaking issues with the Nova but if it leaked around the threads, teflon tape would be my first go to.

I see. Thanks for the tip. Yea, the leaking I have pretty much dealt with by discarding the tubes that leak. My main issue now is just trying to get a nice consistent juice flow into the coils. It tastes great when I first start vaping, but after 4-5 drags, I start getting bad/burnt tasting hits. I have to tip it back and fourth and take like 5 dry hits (without pushing the button) in between drags to suck the juice into the coils so I get another good tasting hit. Some heads are better than others with this. I don't want to have to cut notches into all the rubber caps. It's very tedious. Wish these thing would just work consistently so I could vape non stop, good tasting hit. Lol isn't that what we all want...

Yea, i don't have this problem with every head. It's just certain heads. I think it just has to do with the slight differences in the rubber caps. sometimes the cap can get pushed down a little too far, causing it to either pinch the wicks or just not allow enough room for juice to flow up the wicks into the coil. That's why sometimes, ive had to cut little notches in the cap to allow the juice to flow freely into the coil, resulting in consistent great tasting hits. I just wish these novas would "work" without requiring all this tinkering or modifications. thats why i've been on the hunt for a better tank. but i don't think their is one. the novas are the best. they just need to work out some small kinks and this tank would be flawless.

I have had my Nova tanks (3.5ml) for a couple days now and am experiencing the same leaking issues mentioned above with the bottom threads of the tank. I really do like this setup and really want it to work. I don't mind modifying it to achieve a good end result. I did run some teflon around one of the tank's bottom cap and it considerably slowed it down. I think I will do the other one at work tomorrow but use a little more tape and hopefully that will cure the ill. I do have a question about the tape, however. I am a mechanic and have been using teflon tape for the better part of my life on various pipe fittings with different substances. The thing is, I haven't vaped any of these substances either. Has anyone that has used teflon tape had any issues with it breaking down with the juice? I have heard that some juices are somewhat detrimental (spelling?) to some of the plastic or acrylic tanks. I'm still moving forward with the repair/modification but just curious to know... As a mechanic, I have had just about every automotive fluid in my eyes, mouth ears, or nose at some point but a little concerned about it being vaporized into my lungs. Kinda one of the reasons I quit smoking those wretched cancer sticks.

Sitting down, facing forward.

I wouldn't be too worried about Teflon tape. It's burn temperature is above what a coil runs at and exactly how it would get from the bottom tank threads to the coil is a real question. It's basically "inert" in terms of the liquids being vaped and if you're really worried just put some liquid on the tape and let is sit for a day or so to see if it degrades at all. Heck, there are silicon seals a lot closer to the coil than the tape on the tank base so I don't think it should be a real problem at all.

Just my opinion, worth what you're paying for it. Your results and mileage may vary. No warranty or guarantee is expressed or implied. Proceed at your own risk.

I'm only 2 or 3 weeks into my first Vivi Nova (mini 2.5ml) but have quickly determined how to work around some of the issues raised here. Getting the wicks straight is a problem when you first screw on a new head. I use a syringe needle to fill mine most of the time and use a 3ml bottle when I'm out and about. I just stick the needle into the tank after filling and use it to straighten and align the wicks vertically. That works. Once they are wetted, they tend to stay in place against the center tube that holds the coil head.

When you change the heads, you can't just finger tighten the head. There's a silicone ring that seals the head to the body of the assembly. You have to use a coin or screwdriver to tighten the head and compress the silicone ring slightly. Tighten it snugly but don't tighten it to the point where the silicone gasket bulges.

It's also possible for the coil/wick to bow and not efficiently atomize juice. Press the coil and wick gently with a toothpick when you install it to increase contact with the juice bowl rather than allowing it to bow up into clear air. That helps increase atomization efficiency.

I haven't had leakage yet around the tank threads, but I'm using plastic tanks so that I can see the juice level. Maybe a thin silicone ring gasket or Nitrile o-ring slipped over to the bottom of the threads would solve that issue with metal tanks. I also wipe the interior of the cap and use a paper towel folded to a point to remove juice between the threads and the outer ring of the cap when I refill. There's always some juice around the threads from laying the tank horizontally that gets squeezed out when you replace the cap.

Just my 2 cents.

Maybe I didn't clarify what I was referring to. I know the threading is a long ways (relative) from the wick. My concern was if the juice will degrade the teflon and change the chemical make-up of the kuice. Great idea about letting the tape soak in some juice though. I will give that a try and see what happens. I am primarily using "Casino 21" from mister e liquid right now so I won't have much of a control variety but I think I still have some menthol from when the wifey was vaping. She quit everything all-together. I already informed her that I liked my habit and didn't see any reason to discontinue it lol Hmmm seems like I had that opinion about certain skinny brown colored things wrapped in a white paper casing some time back iirc. I think this time it's ok to say no stoppy though
