The Aspire Nautilus GT Kit comprises of the Aspire GT Tank and the Glint mod and together they look pretty awesome.

Aspire is a well renowned Chinese brand especially when it comes to Mouth To Lung systems.

Aspire Nautilus GT Kit in rose gold

Established in 2013, their current catalogue comprises of 43 tanks, 24 mods and 44 kits.

I should mention Aspire also do Direct To Lung devices like the 210w Skystar mod.

I could use a page full of notable aspire products but to keep it brief I’ll just mention the Cleito series of tanks including the game changing original Cleito – the Cleito Exo and of course the Cleito 120 Pro, all popular among DTL vapers as well as the Nautilus Series, really popular among MTL Vapers.

What Can We Expect From The Aspire Nautilus GT Kit?

Nautilus is one of those product names that carries some weight, even if you don’t know what it is or who it belongs to the chances are you will have hear it somewhere.

There is however, something about this kit that is even more popular than the Nautilus brand.

The Aspire Nautilus BVC coils are probably the best known and most used coils across the entire industry, and yes, this kit takes the Aspire Nautilus BVC coils.

So straight off the bat I’m expecting good flavour and good vapour production.

Designed By Taifun

The Nautilus GT tank was designed by Taifun!

Maybe I’m missing something but I’ve never heard of Taifun!

A quick Google search didn’t provide too much information either. Pretty much all I can tell you at this point is there is 1 RDA, 4 RTAs and a box mod on the market from Taifun.

The kit takes an external 18650 battery, has a 2A charge rating via it’s USB-C port and has a power output from 1watt to 75watt.

Is it the mother of all Mouth To Lung devices or a true All In One Device?

It has variable airflow from a 1mm diameter hole to a 2.5mm diameter hole.

But the only thing about this system that really screams innovation is the battery door which swings open and closed from the bottom of the mod.

Lets see if the Aspire Nautilus GT Kit performs as slick as it looks.

Design and Build Quality

The Kit is available in 3 colours:

Aspire Nautilus GT Kit available colours

Gun Metal, Stainless Steel and Rose Gold. I was fortunate enough to receive the Rose Gold Kit.

Aspire Glint Mod (Battery Section)

The mod has a very typical feel and look to it. It is styled and shaped a bit like many other MTL devices like the Aspire Zelos Kit, for example.

In regards to size it’s pretty huge, it fills the hand and I was going to say it is the size of a single battery sub-ohm box mod.

Aspire Glint Mod in rose gold and black

Then I remembered, it is a single battery sub-ohm box mod, it’s just being marketed for Mouth To Lung users. We’ll touch onto that a little bit more in the performance section.

With the reflective Rose Gold coloured Zinc Alloy on the top and bottom of the mod, black aluminium body and black plastic front the kit looks super smart.

You may also notice the power adjustment buttons are black plastic and the fire button is a reflective rose gold plastic.

Variable Wattage

The variable wattage on the Aspire Glint is pretty standard of mods as it’s simply an up button and a button.

All the way up from 1w to 75w the wattage goes up and down in increments of 0.1w unless you hold the button then it goes in increments of 1w.

The plastic buttons protrude from the mod by about 1 – 1.5mm and are quite easy and nice to press.

Battery Door

I don’t think I’ve ever seen a battery door on a mod like this one.

The battery door is on the bottom of the Aspire Glint mod, it opens by firmly pressing onto the bottom with your finger or thumb and pushing it to the side to swing it open.

Aspire Glint Mod in rose gold and black battery door

There are 3 holes for battery ventilation and you must open the cover fully to ensure the gap on the cover matches up with the battery bay.

Although I think it’s a great design there is a small element that I’m not so keen on.

The connector is a small bump on the inside or the cover, to close the cover the connector presses onto the battery and then bumps over it.

I don’t think this will damage the actual battery but it bound to damage the battery wrap.

Although re-wrapping batteries is easy and inexpensive, I’m not keen on having to do it frequently.

That being said that, while I have been using the device, I’ve made a point of opening and closing the battery door to test it.

After at least 30 times of opening and closing the battery cover it hasn’t yet damaged the battery wrap, so maybe it isn’t as bad as I expected.

I’ve also given the battery door a tug, “trying” to lift it up and break it and it feels pretty secure.

510 Connector

The 510 connectors threads on both the mod and the tank are nice and smooth as expected.

The connection plate is super small, measuring at just 13mm across. Initially I was unimpressed, I mean, who put a 13mm connection plate on a mod designed for a 24mm tank.

 rose gold Aspire Glint Mod 510 connection plate

However I since noticed that the connection plate is ever so slightly raised, by ever so slightly I mean less than 0.5mm, nonetheless, it is enough to keep the tank raised from scratching the mod.

The gap between the mod and the tank is so small, I don’t think it poses any threat to it damaging the connector, by it leaning to one side.

The connector is to one side in the center leaving just a 0.5mm lip around the closest edges.

Aspire Nautilus GT Tank

Although the mod and kit are only available in the colours mentioned above the tank also comes in black.

At first glance the tank is rather reminiscent of the Innokin Zenith Tanks, that’s probably because of the stainless steel glass protection tube.

Aspire Nautilus GT tank available colours

It comes fully part without any specialized tools which is great and even the threats are super smooth.

Top Fill

Inside the top fill cap there is an O-ring to seal the outer of the tank and there is 2 O-rings that go into the center airflow tube to stop leakage from the fill holes.

Aspire Nautilus GT Tank Fill Holes and top cap

The top fill cap is removed on a quarter turn. The two fill holes inset by about 4mm but they are very generous in size.

But there isn’t any rubber bung around the fill holes. I hope that doesn’t cause I problem, although I expect it will.

Nautilus GT Tank Airflow

If precision is your thing then the Nautilus GT tanks is great for you. It has 5 different sized holes.

You can also fully close the airflow, which isn’t airtight but it’s close.

The adjustment ring has a grip and it clicks into place for each hole making it super easy to use.

How to Replace the Coil in the Nautilus GT Tank

While inside inside the tank, the coil is not visible at all because the airflow tube (or chimney) goes all the way from the bottom of the tank to the top with 4 small holes around the base to allow liquid through.

Power Options

I think that’s a bit strange, I looked online and at the present the Nautilus BVC coils only go up to a recommended wattage of 28w (using the 0.4ohm coil) yes the Aspire Glint Mod goes up to 75w.

Initially that seems like a massive waste of available power.

It’s not an entire waste of power though, it just provides room to upgrade your tank to a sub-ohm tank at a later date. Making it ideal as a starter kit for someone that might want to move onto sub-ohm vaping at a later date, that way they can keep the mod and buy a stand alone tank.

A lot starter sub-ohm kits only go up to 80w anyway.

Aspire Nautilus GT Kit – Quick Start

How To Fill The Aspire Nautilus GT Tank

  • Twist the top cap anti-clockwise until the dots on the side align.
  • Lift and remove top-cap
  • Add e-liquid through a filling hole at either side
  • Re-apply top cap and twist clock-wise

When using a new unused coil, leave to stadn for 5 minutes to allow the liquid to soak into the coil. Do not let the liquid level go below the holes on the tube inside the tank.

How To Change The Aspire Nautilus GT Coils

  • Turn the tank upside down.
  • Unscrew and remove the base of the tank
  • Unscrew and replace the coil.
  • Reapply the bottom of the tank.

How To Install A Battery into The Aspire Glint Mod

  • Looking at the bottom of the mod firmly press yout thumb or finger on the 3 vent holes and push to the side.
  • Make sure the door is fully open and insert a batter + side first.
  • Close the battery door.

Glint Mod Functions

  • Turn On = Press Fire button 5 times; fast
  • Lock/Unlock = Press fire button 5 times in 2 seconds
  • Turn Off = Lock device then hold the fire button for 2 seconds
  • Turn off/on screen and lock/unlock ‘+’ / ‘-’ buttons= Quickly Press fire button 3 times
  • Lock/unlock ‘+’ / ‘-’ buttons= Press the ‘-’ and fire button simultaneously
  • Adjust power= Press ‘+’ or ‘-’

If you exceed 10 seconds of firing the screen will display “OVER 10S” while this is showing press ‘+’ or ‘-’ to adjust the continuous fire time between 1 and 15 seconds.

How Does The Aspire Nautilus GT Kit Perform?

For this review I used Got Salt – Peachy Promise (Peach and passion fruit, Nic Salt50PG/50VG) and it’s great!

0.7Ohm Nautilus 2S Mesh Coil

This coil is recommend to be used at 20 – 25W; with that in mind I started at 15w.

At 15w with the airflow set to the 2.5mm hole, it doesn’t feel like you’re getting any flavour or vapour, but it does provide a very small amount of vapour and a very subtle hint of flavour.
Aspire Nautilus GT Kit 0.7ohm s2 mesh coil
Turning the airflow down to the 1.2mm hole does give more flavour, but still seemingly no vapour.

At the bottom of the recommended range; 20w with the airflow set to 2.5mm or 1.8mm, provides a nice fairly prominent peachy taste and a cigarette like vapour production.

With the airflow set to 1.5mm or below seems to be a bit heavy on the chest.

25W provides an awesomely satisfying peach flavour with a fairly large MTL amount of vapour. Again, it starts to be a bit heavy on the chest with the airflow set to 1.5mm or below.

30W is a bit too much for any less than 2.5mm airflow in my opinion.

It is sufficient for Direct To Lung vaping for a puff or two, after that it starts to seem like it’s burning.

Although there is a subtle hint of peach with a nice cloud, I’d recommend sticking to 25W.

1.6Ohm Nautilus BVC Coil

This coil is recommend to be used at 7 – 11W; so I started at 5w.

At 5w, I had to check the mod was turned on, there was seemingly nothing, regardless of airflow.

Aspire Nautilus GT Kit 1.6ohm coil

In search for something, anything, I turned the mod up to 7w. At 7w it’s a little bit strange, with the airflow set to the lowest (1mm) nothing seems to happen.

You get an extremely small amount of vapour and no taste, but if you keep taking puffs the coil warms up and give you a nice prominent flavour with a decent cigarette like vapour production.

In my head the fact it needs to warm up suggests it’s either a rubbish coil design or it’s under powered.

With that in mind I turned it up to 11w. There you go, with a bit more power the coil comes to life.

2.5mm airflow is far too much for this set up, at 1.8mm you get a very small hint of the peach, it’s almost unnoticeable but you do get an impressively large amount vapour for an MTL tank. At 1.5mm the flavour his upped a little bit, but it’s still very weak and the vapour production isn’t noticeably different.

With the airflow set to 1.2mm or 1mm and power set to 11w you get a subtle peach flavour with a nice cigarette like amount of vapour. The vapour isn’t very prominent in flavour but it does leave a prominent peachy taste at the back of the mouth.

In a last ditch attempt to find an awesome MTL flavour I turned it up to 13W.

The search is over, through out all of the airflow settings the coil provides a prominent whole mouth flavour, although the flavour seems more prominent with the airflow fully open.

The vapour production is also satisfyingly perfect.

High VG Liquid in the Nautilus GT Tank

The truth is these coils are designed to be used with 50VG/50PG liquid, and with the tanks internal design (coils are covered) I was skeptical that the small holes would allow the thick 70/30 liquid though fast enough.

But I am pleased to report that both coils handled to 70/30 Juice wonderfully.

I used Juccier Strawberry Mango Crush mixed at 70VG/30PG with no nicotine and it was awesome the vapour production was up (as expected) but contrary to my expectations the flavour was amazing too, at times I think the flavour was even better than it was with 50/50 juice.

I should mention – due to the nature of low power, small coils and thick liquid, the coils will have a longer lasting life if you use 50/50 liquids.

Aspire Nautilus GT Kit – Airflow

I am quite impressed with the airflow on the Nautilus GT, the 2.5mm coil is sufficient for almost resistance free Mouth To Lung vaping which been loose enough to allow quite comfortable lightweight Direct To Lung vaping.

Going through the other airflow holes has a noticeable difference until you get to the 1mm hole which successfully provides a cigarette like draw.

As I previously mentioned, when you adjust the airflow it clicks into place for each setting which is great. It prevents the adjustment band from moving on its own accord and with help from the easy grip surface it makes it super easy to set your desired airflow setting.

Battery Life

I don’t like to talk about battery life with mods that use external batteries because there is so many factors to take into account (battery capacity, the wattage you’re using it at, even the battery brand can make a difference in some instances).

I will say that external batteries are always ideal.

If you are using a 3000mah battery and you’re using the kit at the max recommended wattage (25w) you will get approximately 799 x 2 second puffs; that’s a puff every other minute for 26 hours.

The best thing about external batteries, if the availability to carry extra batteries, if you go out with an extra 3000mAh battery you’re going to be set for a wicked 52 hours!

But fear not if you don’t want to charge your batteries externally or carry extra batteries, the kit is complete with a 2A charger, that will fully charge a 3000mAh battery in just over 1 hour and a half.

1 hour and half charging for 26 hours use, what more could you ask for?

While charging the mod displaying a glowing battery indicator which has 5 segments, the manual doesn’t say so, however I imagine each segment closely resembles 20% charge.

When the battery is fully charged the screen turns off.

Coil Life

I’ve been using this kit for about 4 weeks comprising of very light use for 2 and a half weeks and a week and half of intense use and the coils are going pretty strong.

If used right (50/50 liquid that isn’t overly sugary and used within the recommended wattage) Nautilus coils usually last between 1.5 to 3 weeks.

Does the Aspire Nautilus GT Tank Leak?

I could easily tell you that there is absolutely no leaking, but that isn’t entirely true.

If you remember early in the review I mentioned that there is no rubber to seal the fill holes?

This means about 1ml of liquid ends up getting between the holes and the top cap.

When you remove the top cap that liquid ends up going down the chimney and leaking out of the airflow and creates that horrible gargling.

I also told you that the chimney seals and the outer edge seals. Well thankfully they stop the device leaking while the top is on. In fact without taking the top cap off it doesn’t leak at all.

However more often than not, when I refilled the tank it leaked out of their airflow hole.

Such a shame, it’s so easy to fix and I can’t understand why they would let it happen, they obviously knew it was a potential issue or they wouldn’t have bothered sealing the chimney.

Pros – Tank

  • True AIO airflow
  • Great for both 50/50 & 70/30
  • Easy to dismantle
  • True AIO airflow
  • True AIO airflow
  • looks good
  • Capable of great flavour

Pros – Mod

  • External 18650 Battery
  • Very Light in weight
  • Looks good
  • simple and easy to use
  • Has excess power for changing to sub-ohm mod
  • Innovative battery door

Cons – Tank

  • Leaks when removing Top Cap
  • 1.6ohm coil seems abit under ranked on power

Cons – Mod

  • Big in Size for a MTL Kit

Final Verdict

The Pros and Cons say it all really, it’s a great kit for any MTL vaper or starter.

My concern is many starters prefer a smaller device (in my experience at least).

If you don’t mind the size of it, you need to sum up the pros and cons and decide whether or not the pros are worth the cons.

Personally, I think if the top cap had a rubber / silicone bung it would be absolutely perfect.

But the simple fact there is sometimes leaking when you remove the top cap makes me doubt whether I’d buy one or not.

I should stress the leaking doesn’t happen a lot and when it does it isn’t a lot of leaking.

Harley Vape Mill

Vaping since (2012), back when choice was limited. I was rebuilding my RDA and powering it with the awesome the Vamo V2. In 2019 I’ve opened a “Brick and Mortar” vape shop, a Vaping Mystery Box service and launched a YouTube channel that’s already gained 500 followers. Between Vaping and family, i don't often have a second to spare. My YouTube subscribers have already dubbed me “brutal”. What can I say? I’m here to do honest reviews, not a sales pitch.

aspire-nautilus-gt-kit-reviewIt dropped 3 points for not sealing the fill holes, I'm still gutted about that. So although at the recommended wattage the 1.6ohm coil was rubbish, above the recommended wattage it was awesome, so I was generous there. The Flavour from the 0.7 was good, but it's not the best so that can settle for a 9 too. The 7 for replacing is a bit harsh, but it's honest. (on average it will receive a 4.4/10, I think that's perfectly fair). Nice try aspire, you also made perfection.


  1. Hi Harley, this is a perfectly detailed review!
    My two Nautilus GT (3ml glass tank and 4,2ml polysulfone tank) brings absolutely no gargling or leaking if I: 1) close the air before refilling, 2) fill carefully so not exceed hole level from both holes, in horizontally position. I hope I helped.

    • I have tried this but as per the review the liquid still goes down the chimney and causes gargling. Why? Because even if I close the airflow and don’t overfill, liquid still ends up in the top cap from simply tilting the tank, and when the top cap is removed, the chimney is no longer sealed and the liquid runs down the chimney and into the coil. I think I’ll be bottom filling from now on. I’ve also had some issues with air locks with this tank, which is annoying. The tank looks great aesthetically but it’s far from perfect. Haven’t had any issues with Aspire nautilus 3 tank however.

  2. hi your reviews do seem good and honest and seem much in line with my thinking so with your knowledge which tank would you say best for MTL .FLAVOUR AND NO LEAKS

  3. Hi,

    Just recently brought an aspire gt after reading your review on here of it.

    I am currently using 1.8 coils and the E liquid is Titan mint 70pg/30vg. The problem I am getting is a lot of gurgling and it feels like I am sucking through a straw.

    I am a mtl vaper and using system at 14w

    Any hints and advice appreciated on if I need to change e liquid or coil strength



    • Hi Clair, As you may know, the gargling suggests there is excess liquid in the coil or base of the tank.

      This could mean either, the liquid is very slowly leaking into the coil (which in this case i highly doubt because you’re using 70/30 with the 1.8ohm coil)…

      OR, there is excess liquid in the coils, from when you installed the coil or filled the tank.

      To fix this get a bit of tissue and wrap it around the airflow (very loosely) and blow into the tanks mouthpiece once, fairly hard but not as hard as you can. Doing this will blow out any excess liquid. The tissue is there to catch the liquid, instead of it splattering everywhere.

      After this the gargling should have gone. (If not try just 1 more time- with the airflow hole facing downwards).

      If the gargling comes back or it starts leaking through the airflow hole before you change the coil again, then it is likely either the coil isn’t installed properly or the coil is leaking.

      Let me know how you get on. FYI this is also transferable to all tanks and coils.


  4. 3F Vape do a cheap as chips ‘styled tribute’ version – *coughs* – I may or not – I couldn’t possibly say – be ‘interested’ 😉

  5. Taifun’s are very special – never owned one but had a toot on one – can’t remember which – but yes it was a surprise teaming up with Aspire!

  6. Taifun is one of brands that not everyone knows about but it is held in high regard, moreso for their rta’s which is why some people were surprised when they teamed up with aspire as taifun falls in the high end category. I love the design of the tank, the mod is so so and nothing special but does the job, overall a great combo
