Introduction – The Siren 2 GTA for MTL By Digiflavor
The Digiflavor Siren 2 is a welcome addition to the world of mouth to lung (MTL) vaping. As the name implies, Digiflavor is all about maximising flavour for vapers.
This young Shenzhen brand specialises in atomisers of every description and based on my experience with a good number of their products, they succeed with flying…flavours.
With atties like the Pharaoh RTA, the Pilgrim GTA and the Drop RDA, these guys have been hot on instagram and throughout the vaping community because not only does their gear vape pretty dang well, they are pretty sexy on the surface too.
The Siren 2 is advertised as purely a Mouth To Lung GTA but I feel they are selling themselves short. Read on to find out what the magnificent Siren 2 can do for Direct to Lung (DTL) vapers too.

Build Quality & Design
Now…I have a lot of tanks but I was blown away to discover, through the clear plastic packaging, that I’d just received the most beautiful tank I own! I have the blue Siren 2 and it is, according to myself, aesthetic platinum.
Sleek and simplistic, with no heavy knurling anywhere to detract from the gorgeous finish which is actually somewhere interesting between matte and metallic. This doesn’t make sense but it looks like matte metallic blue, it’s just special. Oh…it’s all stainless steel BTW.
I can see the deck housing, with an elegant Siren Logo on it in a gold pearl against that strange blue.
The deck is half way up the height of the juice chamber in GTA style and the base reveals an adjustable airflow system of 5 holes that increase in size, from the smallest on the right to the largest on the left.
The smallest holes are TINY…so it looks like this is definitely going to work for MTL, with the full airflow likely just enough for a very restricted lung hit, build dependent, but we will have to wait and see.
The 15mm drip tip is 9 mm wide, so definitely narrow and long enough to further restrict that (sneaky) lung hit and really condense the vapour for that MTL throat hit.
It’s tipped with a 6 mm polymethyl methacrylate or thermoplastic section which protects from incident overheating, as well as being hygienic and safe.
The drip tip is 510 and removable!
The top cap is a 2 tier affair, with almost invisible grooves or knurling on the lowest tier, 2 either side. The tiers, in combination with the long tip create a unique, palace spire sort of look that in combination with the name and this finish, is just stirring my inner depths and making me think of all kinds of fabulous things.
The top cap is a twist and pop, as opposed to an unscrew and the fill slots are easy to use with almost any ejuice bottle.
Unscrewing the glass from the base, the deck is revealed, suspended by a silver bar seating. I discover a two post system with massive single terminals in each post and big cutouts both side the deck to show you how to place your coil and to channel your wick down beyond the deck and into the juicy sea of dreams.
So…this is, it seems, a single coil deck but I am looking at this massive space, these massive terminals and wondering, is it legal to put such a big coil in a MTL GTA, such a one as the one I plan to use first? With a chunky coil I can test deck space, run a higher wattage and see what a VERY warm MTL vape is all about.
This looks good, let’s see if she vapes as good as she looks and feels.
Everything necessary is included, a cute little multi-screwdriver which, in spite of product pages from the brand, I refuse to call an allen key because it isn’t one…language barrier, I’m guessing but who knows? Multicoloured o-rings will allow you to funk up your Siren.
I have a grand obsession with unlikely set ups and colour matching in odd ways and consider myself rather talented at it. Check out this bewitching mix with the iJoy Capo 100, red o-ring on the Siren 2 and a custom drip tip…
How Does The Digiflavor Siren 2 GTA Perform?
I’ve been devouring juice at an alarming rate on my massive DTL sub-ohm tanks, not to mention the constant battery changes required at high wattages and for me, the Siren 2 is exactly doctor’s orders.
The airflow and drip tip are brilliant for MTL right through the 9 optional settings.
A high ohm, low wattage coil like the included one provides a cool but cloudy and flavourful MTL, warming slightly with restriction. Increase coil size, decrease resistance and heighten wattage to warm that vapour up and enjoy the complexity some flavours give with heat.
DTL vapers who’re vaping with higher wattages, don’t poke fun at 20W because when you go ahead and DTL vape a 1 ohm coil on this baby, provided you love a very restricted hit, wow…who knew?
On DTL I’ve enjoyed cloud and flavour that the airflow on sub-ohm tanks fools you into thinking are impossible with such low wattage: the Siren 2 will show you different, if you’re okay with serious flow restriction.
Vaping 20W on the iJoy Capo 100 with a nice big 20700 cell and a 1 ohm simple Kanthal coil with 80%VG, I experience the same flavour and vapour production I get from, say, 50W on 0.5 ohms. My battery will last me 3 days, plus the heat and restricted draw (very restricted) intensify flavour to the max.
Are you kidding? Yup…the horizons are endless for the intrepid vaper.
It isn’t just an airflow thing though, the GTA system also does its bit here.
If you’re a lover of restricted lung, this tank will rock your foundations with a smaller build, trust me.
The Digiflavor Siren 2, in my opinion, is awesome.
So for cool MTL with out of control flavour and cloud, or low wattage and juice consumption restricted lung with great flavour and cloud, use a high ohm, simple build.
A 0.5 ohm , 6 wrap, alien wire build at 60W (since a bigger build needs more wattage to heat) and I’m getting a warm and rich MTL hit like I’ve literally never had before. For DTL though, the great big coils generate too much heat for this level of restriction, not only does the tank get very hot but your lungs won’t be able to handle that scalding vapour.
So low ohm, heavy wire, high wattage on the Siren 2 means hot MTL and only the occasional gun-hoe DTL hit. Got it.
Well crikey…it seems this tank does vape as good as it looks and what’s more, I, who enjoys my DTL vaping, have found a way to make everyday use of the most beautiful looking tank on the block, without having to convert…while saving battery power in the process. Can I get a whoop whoop!!!???
Yes, okay Digiflavor…we get it, this is an MTL GTA but there are ways around these things. What are reviewers for if not to tell you what IS possible and not what the box says!!!! Anyway, I’m hoping this review gets some DTL lovers on the Siren 2 bandwagon because just look at it, it needs to be seen!
How To Fill
- Twist the top cap counterclockwise
- Fill through a slot
- Replace cap
Ease of build
This deck is an absolute pleasure to use, with ample terminal space and a considerable deck length to allow for even the largest coil.
Most premade coils will have leads facing the same direction so be sure to check that or else wrap your own as messing with alien wire, fused claptons etc to try and reshape them is very likely to compromise the integrity of the coil and result in hot spots.
The threading on the screws is great and they are very easily accessible.
A fun build with no space issues and also very easy wicking.
What I Liked
I’m crazy about the looks, as you know. The airflow design is top notch, the GTA system is a winner and the deck is easy and very accommodating. I like the potential for a cloudy and flavourful DTL vape on a plus ohm build with the Siren 2, as well as the potential for a truly warm and rich, high wattage MTL with a lower build.
What I Dislike
Sorry, no can do.
Final Review Verdict
Here is a GTA that’s shown me some serious potential for MTL lovers to experience warm, high wattage high VG vaping.
Really decent cloud and the joy of doing your own builds, all on an atomiser that’s big, beautiful and maximises flavour at every turn and for DTL users to enjoy the gutzpa that restricted airflow and the GTA system puts behind a low wattage build, saving you power and juice in the process.
The Digiflavor Siren 2 GTA is versatile, it’s sexy, it’s tasty and I love it. I highly recommend this one.
- Sleek and stylish aesthetic
- Large 4.5 ml capacity
- Easy to use deck allows for even the largest single coil builds
- Wicking, airflow, coil space and GTA chamber height all maximise flavour
- Great flavour and cloud with the option for anything from a warm to a cool vape and even restricted, low wattage DL with a difference
