The Siren range were created for Mouth To Lung (MTL) vapers and so far there has been the original Siren GTA, Siren 2 GTA, Siren 3 RTA (found in the Z1 SBS Kit) and the recent Siren 4 RTA.

MTL is a vaping style – we tell you more about this in our Guide To MTL and DTL Vaping.

Firstly looking at the Siren G Tank – this is not a rebuildable like the previous versions but this uses the Geekvape G Series coil range – already used in the in the Wenax range, G18 Vape Pen and Aegis Boost kit.siren g coils

The kit includes the 1.2ohm and 1.8ohm G Series coils to get you up and running.

In standard format the tank has a 4ml e-liquid capacity which is refilled via a leak-proof top cap. I have not seen a mention of a 2ml version for release in TPD Regulated areas as yet.siren g tank features

You can adjust the airflow to your preference and Digiflavor say there are 10 different airflow combinations.siren g airflow

The mod is a tube style which can be converted to use either a single 18650 battery or a 18350 battery. As usual the battery is not tube battery

The output is decided by the mod according to the coil installed but you still have a choice of 3 output levels of Low, Medium and High. An LED indicator informs of the power level selected.s g tube output

A mechanical rotate lock is fitted to the mod – but it is not very clear as to what this actually does. I am not sure if this just locks the fire button to prevent accidental firing or whether this is to prevent the tank being removed to make it childproof?sg tube lock

There is a USB Type C port which can be charged at up to 2A charge rate for use in emergency when an external charger is not available.

There are 4 colours to choose from: Stainless Steel, Gunmetal, Black and Rainbow.

My name is Michelle - I am 46 and an engineer and Technical Author by trade. I started vaping many years ago in the days of Tornado tanks, Ego batteries and Variable Voltage. My journey in vaping began again a few years ago and have started to move up in the shiny shiny gadget department and love vaping! I have finally stopped smoking as of June 2019 and that is all thanks to vaping! 20mg Nicotine Salts are my hero! Oh and I am partial to a nice pod mod!


  1. I love the way the Digiflavor SG MTL tube kit vapes. The flavour is excellent and it’s super smooth. One battery charge usually lasts me 2 or 3 days and I get a good 2 weeks out of a coil.

    The one thing which kills me about it, and it’s almost a deal breaker, is how stupidly hard it is to change the coil. Not the actual changing of it, but getting the cap part off to access the coil. All the components of the tube kit screw off in the same direction, so when you try and unscrew the section just above where the tank is attached to the tube, you can also unscrew the plastic tank from it’s base, the drip tip from the tank, and the top metal section between the drip tip and the tank. For whatever reason, the coil section cap was so tight, that all these other bits came off before I even came close to unscrewing the part I wanted. After trying rubber gloves, grippy jar opener thingy, and the freezer, I only got it unscrewed by dunking it in hot water for 10 minutes, letting it cool a bit, then gripping one tea towel wrapped end with pliers and twisting off the cap with the grippy jar opener thingy.
    No chance at doing a quick coil change with juice in the tank, and of course I had the last of my fave juice in there when the coil blew out.

    I’ve since tried priming the screwy bit with e-juice, with vegetable oil, adding an o-ring (no idea if that would have helped, but figured it was worth a shot) all to no avail. I have to go through the same ordeal each time the coil needs changing. Lucky each coil lasts a couple of weeks, otherwise I would have tossed it long ago.
