Introduction: The IGVI M2 Sub Ohm Tank from Yosta
The Yosta IGVI M2 tank is a new sub ohm tank which uses mesh and standard coil heads.
There have been a couple of IGVI tanks plus an RTA and an RDA.
The IGVI M2 has a 6ml bubble glass installed and also a 2ml TPD compliant glass in the kit – in the EU you will probably only get the 2ml glass.
There are 2 coil heads for this a stainless steel 316 standard 0.5ohm coil and now a 0.15ohm mesh coil. Also the Yosta website says the coils are compatible with the IGVI P2 tank and also SMOK TFV8 Baby range – excellent!
There is a top fill cap which slides across to reveal the filling port.
You also get a bottom adjustable airflow ring wrapped around the “avoid condensate base” assembly. The “avoid condensate” system is basically an extra bowl kind of affair in the base to prevent liquid or condensate exiting through the airflow intakes.
Choose from Black, Silver or the 7-colour rainbow style.
Thank you to Yosta for sending this over to me for review but as always I will report back honestly on my experience with the device I received.

Build Quality & Design
I received the Yosta IGVI M2 tank in the Rainbow 7-Colour version and it is very very pretty.
The 6ml bubble glass and mesh coil are already installed.
There are no instructions – which was a bit odd – I was trying to open the tank to see the writing on the coil and couldn’t get the base off initially – and was scratching my head a bit as some tanks can be push in coils from the top etc.
Looks wise this looks great the bubble glass gives a great capacity and a sliding top fill works smoothly. A little arrow on the top cap indicates where to push to refill.
The airflow control ring on the base has punched out holes for airflow inlet and they look great too.
The early images of this tank did show a cobra style drip tip but mine only had a plain black which is a shame as I think the cobra style really did look good.
This does have an 810 drip tip – I did try the two styles the Goon style (on the left in photo – without O-rings) which was too loose and the standard 810 (with O-rings shown on tank) which was perfect.
To get this tank up and running just fill it up, allow the coil to prime, adjust the airflow and you are off!
The mesh 0.15ohm coil head is already installed in the tank but you can swap this for the SS316 coil in the kit.
How To Fill The Tank
- On the top of the tank is a little arrow, push the top cap across at this point.
- The filling port will be exposed.
- Add e-liquid to the tank watching the level through the glass.
- Slide the top cover closed.
How To Install The Coil Head
I will mention as there are no instructions in my kit I had a bit of a struggle for my first coil change.
The bottom cap did not want to unscrew. I didn’t want to force it too much in case there was some kind of special push in design. However in the end I got fed up and got the pipe grips on the tank base and got it open eventually.
- Remove the tank from the mod.
- Turn the tank upside down.
- Unscrew the tank base – mine was tighter than a gnats nether regions!
- Unscrew the coil if one already installed.
- Screw a new coil into the tank base.
- Replace the tank base onto the tank.
- Fill the tank as described above.
- Leave the tank to stand for 10 mins – especially with the mesh coil – a dry hit with a mesh coil is like drinking petrol (yeah I do know – siphoning out a fuel tank mishap in my past…)
How Does the Yosta IGVI M2 Tank Perform?
Flavour & Cloud Production
I used the Yosta IGVI M2 tank on my Yosta Livepor 230 Box mod – seems only fair as they are related eh! I set the mod to variable wattage and “Normal” taste mode.
My e-liquid, because I am boring and don’t experiment much, is my usual Stika Bombz Fruit salad, 80%VG and 6mg nicotine.
Airflow wise fully closed you have no airflow and fully open there is a slight restriction – i.e. not as “airy” as say a Smok TFV12 Prince – but not sucking the underwear up from your bottom either.
Also worthy of note is the fact you can also use Smok TFV8 Baby and Vaporesso GT coil heads in this tank. I did try both – my coil heads were knackered so I didn’t fire them up however they did fit perfectly.
Mesh Coil 0.15ohm
So I started off at 50W with the coil as there are no instructions with the tank and I can’t read the tiny writing to give me a clue of the rated wattage.
At 50W this was an acceptable vape – slight flavour, bit cottony and some vapour. Let’s crank this bugger up and see how it fares huh!
Going up to 60W and this has improved significantly.
I have quite a few mesh coil tanks with 0.15ohm coils and they usually don’t come alive until over 70W onwards.
And this was the same, 70-75W was far better. It did take about one tankful of liquid for that slight cottony taste to fade but now lovely flavour.
After 3 tankfuls this is purring away lovely – a great little tank so far!
This is not quite in the same league as other mesh coils I have used but perfectly good and still better than a lot of standard coil sub ohm tanks I have used. Well played Yosta!
Also to add this coil has been going for 7 days now and still tastes great and cotton is still white – I am only swapping it as I need to test the SS version!
SS316 Coil 0.5ohm
This is rated 30-60W on the Yosta website – it didn’t say on the box and I didn’t have any instructions. The text on the coil head is far too little for me to see.
So because I am hard I started off at 40W with the airflow on my usual mid setting preference.
As expected quite a cool vape and cottony taste – this did improve on the mesh coil after a tankful so I won’t judge it just yet!
At 50W this is performing quite well – not as warm vape as the mesh coil but pretty smooth and a lot more vapour than I was expecting!
Up to 60W and there is slight spitting but again this is the first tankful of liquid through this coil – but seems to have a bit more flavour and still rucks of vapour.
I did take it to 65W but got the warning taste of lots of cotton so didn’t want to push it any further.
I have now had 4 tankfuls of liquid through this coil and the flavour has improved and the cottony taste has now gone. 60W was my preferred power setting for this coil.
After using the mesh coil the SS316 coil is pretty “Meh” but again not terrible either.
- Lovely looking tank in the rainbow
- Very easy to fill
- Pretty good flavour from the mesh coil
- No leaks
- Assembled and built well
- Coil life from mesh coil is excellent
- Quite efficient on e-liquid.
- Also compatible with Smok TFV8 Baby and Vaporesso GT coil heads
- A nice drip tip would complement this.
- No instructions
- Tight tank base
- I wouldn’t bother putting the SS316 coil in the kit- just put two mesh coil heads in instead
Final Review Verdict
This is how I see it – this is a good sub ohm tank when you use the mesh coil.
But this tank with the mesh coil is still way better than a standard coil tank – the mesh coil life of over a week and flavour above and beyond what a standard wire coil head can offer does go in this tanks favour.
The SS316 coil in the kit – was decent and ok performance but after using the mesh coil it did seem bland and weak. In fact if I was Yosta I wouldn’t put this coil in the kit at all – just put 2 mesh coils in instead.
The tank was robust, well built, had zero leaks and it isn’t as greedy on liquid as some I have used.
I wouldn’t put this at the top of my list to purchase but it wasn’t a disappointment either.
