Unfortunately, it confirmed to me that this particular one is defective. It constantly leaks from the small hole at the bottom that is there for airflow. No sealing at all, and with every refill you have to be near a sink to wash your device and your hands.

It's definitely worse than the Zlide, with 10 puffs all the liquid is gone. I'm tired of refilling. At night you can't find the right air hole. As for the flavor, I don't see anything superior compared to other atomizers

Very good atomizer, but the coils it takes are the worst. Max 20 puffs and you need to change it. Specifically, the Aspire Nautilus Aio 0.3ohm coil at 28w operation

I had the Nautilus GT and after getting tired of the leaks I decided to get the Nautilus 3 in 3 ml. No leaks, perfect performance. So satisfied that I also got it in 4 ml.

3rd day very satisfied, I have found my puff with the 0.7 at 20 watts in the 3rd air intake position, completely satisfies me, consumption ~150 puffs/ml, combined with the aspire mod and it is very beautiful

For factory settings, you’re all set. No leaks, very good taste, especially with the 0.7 mesh. I just wish the air holes made the click sound that the previous versions had because at night I can’t recognize them (especially if the atomizer is black).

Leaks, leaks, leaks. Already from the second day it started losing large amounts of liquid. I had the Nautilus 3S with exactly the same problems and thought I’d get the Nautilus 3 in case it’s better. In the end, a HUGE flop as well, a complete disaster for both. Wasted money. Their construction keeps getting worse and worse. In the end, only the name remains.

This atomizer is the complete package for anyone who wants to get "something good" and never deal with it again. It is versatile and provides options. Its coils are of consistent quality. It is excellent with its 0.7Ω mesh coils. For something closer to a lung hit with a larger airflow, it also has the 0.3Ω mesh option. Flavor as good as it gets, performance has been steady for years.

4 stars instead of 5 because once the rubber gaskets around the hole to fill the tank broke, and that is not something that can be repaired, so I had to buy it again. Since then, however, I haven't encountered such a thing again; it might have been a problem with the first ones that were released back then.

Closing in on 1 year of daily use of Aspire Nautilus tanks (I have two 3s and one 3S). The flavor they provide is more than satisfactory using (cigarette-style use only) 2S mesh coil resistances at 20-25W for most months, switching to AIO 23-28 because it suits me better at 25W, which is what I vape.

As for the LEAKS, I must draw your attention to the way you fill the tank (this applies to all tanks that have airflow below and are over 2ml). WE ALWAYS FILL WITH THE AIR CLOSED AND THEN TURN IT UPSIDE DOWN, OPEN THE AIRFLOW, AND THEN TURN THE TANK BACK TO NORMAL AND AS IF BY MAGIC, IT WILL NOT LEAK A SINGLE DROP AGAIN

It really has a very nice draw for people like me who never do RDL and MTL, and it's convenient to change it every now and then. However, the positives stop there. There is no way to change the airflow if it's dark; it would be great if it had a click. A cheap atomizer with ancient coils. I don't understand why Aspire doesn't make such a nice airflow in new atomizers with nice new coils like the Atlantis GT, and everything has to be either DL or crappy pods. Get it to play around, but don't expect anything crazy. Companies are only focusing on pods now; we won't see any improvement. Also, throw away the drip tip as soon as you open it and put your own on

I had the Nautilus 3s which I liked a lot, after many drops it got a little dented on the cap before the mouthpiece. It opened somewhat easily and out of fear that it might leak on me, I replaced it with this one. There are no serious differences in quality. The new Nautilus holds more liquid, which is good (fewer refills) and bad (the liquid's flavor deteriorates faster). Otherwise, very good for my taste.
Best MTL coil for my taste (13-15w) is the Aspire Nautilus Mesh Coil 1.0ohm. Big difference in flavor compared to any other at these watts.

Perhaps the most wasted 20€ I have spent in my life, it constantly leaks liquids and I change the coil every 5 days. Whoever buys it will regret it... the vaporizer is trash

I had the 3ml gt for years.
We're talking about a tool!
No juice leaks at all.
This one here runs. Out of the blue.
And it sucks the juice.
Why Aspire?? What did we do to you?

And let no one rush to say their clever remark.

I've been vaping for 10 years. I might have gotten a defective piece.
That's what I see, that's what I say.
I can't stand the Zeniths.
This metallic taste they all produce bothers me.
Aspire released a couple more recently, I'll give them a try.
I like a 5ml tank without leaks, with Nautilus flavor, silent, preferably 25, 26 diameter.
Am I asking for too much? I'll wait and see if they come through.

I believe it is easily among the top 3.. flavor and zero leaks, comfortable to use.. full vfm and much more!! With the 0.7 mesh, I don't know if there is anything better or truly equivalent…. those of you who are new and considering it, go and get it tomorrow already!!!

Very powerful vaporizer. Possibly the best MTL. Literally zero leaks. Aspire has made something very good. I use the Mesh Coil 0.7ohm and the BVC 0.4ohm and I haven't had any problems. The airflow has many options, the construction is sturdy and beautiful. The slide fill is very easy. It looks great with my Geek Vape. The coils are changed in record time without emptying the tank. And with the 0.4ohm coils that I vape at 28w, with the airflow fully open, and the 0.7ohm coils that I vape at 24-25w, the vapor and flavor are sufficient. I prefer the 0.4ohm coils a little more.

I bought it as a set with the modaki zelos 3 l... the atomizer is incredible. In the past, I had started smoking due to leaks with the nautilus 2... this time there is no comparison. Also, for those who want to get involved, there are related videos on how to repair the coil. Since the day I started making my own coils, I have seen a huge difference in taste and vapor. Also, I use it in CPS mode of the mod that I have adjusted as I like it more

It worked properly only while using the pre-installed coil. When I changed the coil, leaks started. It leaks whenever it feels like it from the air holes in large quantities and there is no remedy. It's not even good for trash...

I bought it 2 weeks ago and I am very satisfied!!
After all, I have been a fan of Aspire for years, having the small one at 2ml, but I struggled to open it to fill it up!!
For anyone who smokes, it is a very good choice!!
However, there is also the Geek Vape Zeus which is also very good!!
Of course, with 2S 0.7ohm mesh coils!!

I bought it because I wanted to replace the nautilus 5ml which worked like a dog for the last 3 years and no matter how many tests I did with other vaporizers, they all failed, leaks, etc. Quite skeptical about some reviews but I had no other choice since the previous nautilus is no longer available anywhere and I wanted to take a risk by trying at least the same brand. The vaporizer is PERFECT! It hasn't leaked at all in the 2 months that I have it (I was expecting it in the corner after some reviews), with many airflow options, its supply is very easy since you don't even need to unscrew it. I highly recommend it!

It's fine now, some people mention leaks, I don't know what you're doing to it, this one doesn't have any leaks at all, on the contrary, it has a very good seal. Maybe your brain has a leak, without misunderstanding or you don't know how to use it. Those who have bought it from me have no issues, that's why I decided to purchase it. The taste is very good. Overall, it's good for its price and generally nice.

Coming from the Justfog Q16 pro for 1 year, the mtl vaping has reached another level.
I paired it with the geek vape s100 and the pre-installed 0.7Ω coil of this atomizer, where my first impressions were excellent.

Positives:
-Easy filling
-Drip tip for both mtl and various accessories
-Good price
-No leakage when changing coils
-Large tank
-You can choose from a variety of coils for all tastes
-Available in different sizes for the tank (2, 3, 4 ml), diameters (22 and 24mm), and in many colors.

Negatives:
I didn't find anything. If I do, I will come back.

Coming from the Nautilus 2, it is the ultimate choice.....leak-proof, easy filling, proper cigarette-like draw.....

I bought it by going to stores and asking for something without leakage. After the first fill, only leaks, nothing else

Unfortunately, it has many leaks... suddenly, when you least expect it, it can spill liquid on your hand or in your pocket. Sometimes it does it when it tilts enough, other times it does it while standing up for no apparent reason. I have stained hands, pants, desks, etc. You always have to have tissues with you, many times I entered shops and asked for paper...
Another thing is that when unscrewing it from the mod, it unscrews the top part with the glass first and then the base, resulting in if you don't pay attention, all the liquid spills on you... Also, sometimes the filling head can open, putting it in your pocket, it doesn't close tightly.
The taste is very good as we know it from Aspire, but what can you do, you can't use it with so many leaks. After a few months of use, I will retire it, it has tired me a lot.

I have been vaping for 3 months now after 12 years of smoking. I started with an Innokin Zlide which was a complete disappointment. I tried every coil but none of them gave me the long-lasting, heavy/tight draw that I was looking for. It was too airy for my taste, so I switched to pods because their draw was closer to my liking.
A few days ago, I decided to give mods another chance and chose the Nautilus with the 1.0 mesh coils, and finally, I found the tight draw I had been searching for all this time, and the flavor is also much better. It has many airflow options, so if you want it to resemble a cigarette, there's definitely one that suits you. It also doesn't leak at all. 5/5, by far better than the Zlide.
I will come back if I have any problems in the future since it's still fresh.

Really. Where to start and where to finish.
It is indeed a gem and not just for its appearance but also for its functionality.
Use maat rank. Really bad or simply for throwing away. I decided to try the nautilus because I needed a more cigarette-like puff without leaks. I was shocked! Filling, cleaning, and most importantly, no leaks; it's the best thing out there! No leaks so far. Easy filling and also no noise!
I use it with a 0.7 resistance at 20-23w.
Don't even think about it, it's not a waste of money!
1000% guarantee!

Edit: with the 0.7 at the mentioned wattage, it doesn't last long, so it needs to be changed. Maybe it needs lower or smoother liquid.
However, with the 1.8 resistance at 8-10w, it's the best. The flavor and duration are much better than the 0.7 resistance.

Leaks..... leaks..... leaks..... leaks..... leaks..... What a waste of money! After 3 weeks of use, it ended up in the drawer! It sucks up liquid, the liquid escapes onto the mod above..... I took it to the store where I made the purchase and they gave me another one.... Same issues with the other one! Unfortunately, it doesn't work. I got the Innokin and I was saved!

Jewelry! Aspire flavor....!!!! Solid construction! No leaks so far! Hopefully the problems that previous ones had with leaks have been solved because the vaporizer has no competition!!!

The draw and the airflow are the classics of Aspire. Don't expect anything more, I have tried the Mini, 2, GT, and now this one and they are all the same. They suit me because they are durable and reliable.

Zero leaks. None.
