Hi Vaping Underground members, In this review i take a look at the Siren V4 MTL RTA from Digiflavor. The Digiflavor Siren V4 MTL RTA was supplied for the purpose of this review by Allison from Geekvape.
S MTL RTA V4 - Digiflavor
Introduction
Geekvape's sister brand Digiflavor have a few favourite series in their camp but maybe the one which is held in the highest regard especially amongst MTL vapers is the Siren with the Siren V2 22mm version still regarded as one of the very best MTL RTA's ever to be released. There was a long wait for V3 and if that was a little disappointing to some it's been swiftly followed by the V4 which see's a radical makeover and semi-hidden bottom airflow design. The V4 comes with 2 different drip tips including the Siren style and 4 different coils, let's check out the Siren V4 from Digiflavor!

The Siren V4 came in sample packaging that consisted of a Red cardboard box with outer White cardboard sleeve, we have the "Digiflavor" logo front and contents etc on the reverse! I received the Gunmetal version, the options are Gunmetal, Rainbow, SS or Black.
The Siren V4 is a very short 22mm MTL RTA with just a narrow PEI viewing tube which is frosted on the Gunmetal and Rainbow versions but Ultem style on the Silver and Black versions! The top cap steps in and has fine aggressive knurling, we then have a very long narrow drip tip. On the main sleeve we have the "Digiflavor" logo printed on the front which looks ok in my opinion but may not be to everyone's liking. On the base section below the frosted tube and on the airflow control ring we have the same fine aggressive knurling to match the top-cap. Between the two we have an indented section which includes airflow markings and a Red dot on the AFC which can be lined up against those markings!
Moving to the base we have a Gold plated Brass pin that protrudes and printed branding and safety markings. It's a noticeably small and short RTA and in my opinion quite a looker!

What You Receive?
As well as the Siren V4 MTL RTA with pre-installed long narrow 510 drip tip you also receive what i would describe as a Siren style shorter (but still quite long) alternative. I would imagine it's more to do with mine being a sample but the alternative drip tip didn't have the O-rings fitted so was loose but were in the bag of O-rings and spare grub screws so needed installing.
So that's the spares bag mentioned so on to the two packets of cotton and coils! One packet has 2 different 2.0ID coils which are a MTL fused clapton (1.2ohm) and a MTL Clapton (1.4ohm), you also receive 2 shoelace cotton pieces. The second packet consists of two 2.5ID coils which are a Braided Coil (0.65ohm) and a MTL fused clapton (1.0ohm), again you receive a further 2 shoelace cotton pieces, finally you receive paperwork!

It's Various Parts!
Up top we have fine aggressive knurling on the top cap which sounds a little squeaky when unscrewing and securing but actually feels very smooth! We have a narrow, very long drip tip pre-installed which can be swapped for the Siren style drip tip which in my opinion despite the V4 having a complete aesthetic overhaul and being much shorter still becomes visually a Siren in appearance with this drip tip installed, I like both!
The next section is all one piece which includes fill plate with two fill ports, outer sleeve, chamber and narrow PEI tube, you don't get a spare PEI tube but maybe that's because it can't be removed, at least i can't find a way of separating it from the sleeve which if is the case must be a con because if it cracks the whole top section needs replacing!
The deck section has a 2 post GTA style deck with shower head airflow holes underneath where the coil will sit. We have an AFC which can be removed which has a Red dot for lining up with the airflow markings!

Filling
The Siren V4 has a 2ml capacity and top-fill design. As mentioned even if it doesn't sound it the threading is nice and smooth and removing the top-cap reveals the fill plate to be indented allowing any spill to find it's way into one of the fill ports which are not huge but big enough for most nozzles.
