I’m glad to be back yet again with another review for you. This go round I’ll be taking a look at the Digiflavor Siren MTL rta V4 that was sent to me by Geekvape in order to provide a fair and honest review. I am somewhat familiar with the Siren series of rtas. I have used and still to this day use the Siren V1. I bought two of the Siren V2 when they came out but honestly didn’t care much for them. I also have a couple of the Siren V3 that were included with the Z1 SBS kits. I like the V3 well enough although felt like the flavor production was a little lacking. So here we are now with the V4. It’s really different looking compared to past versions and I have high hopes for this one despite it only having a 2ml liquid capacity. Let’s see how it goes.

INITIAL THOUGHTS:
The packaging of the Siren V4 has an outer white outer sleeve with a red two part box underneath. The one that I received is the gunmetal version. Like I mentioned earlier, I have some experience with all three prior versions of the Siren RTA. I knew from seeing pictures before receiving the sample that it looked quite a bit different from prior versions with an almost invisible tank section and what appeared to be a very long drip tip installed on it. I tried both of the included tips but really didn’t care for either that much as you can see in the picture below that I have installed one of my own 510 tips.
The Siren V4 is 22mm in diameter and about 51mm in total length. It is an MTL tank like previous versions but is quite different in design. It has a PEI 2ml tank section and includes a spare glass tank. It has center located honeycomb airflow holes and allows the airflow to come up directly under the coil. It has a leak proof bottom airflow system and a semi hidden airflow control system. It really is quite different from other rtas in the Siren line.
What I’m going to call the front of the tank has the Digiflavor logo on the top section of the tank with the barely visible tank section below that and the airflow control below that. There are multiple holes and a red mark that allows you to keep track of where you have the airflow set. It’s a rather nice feature in my opinion. The top cap of the Siren V4 takes about two and a half complete rotations to screw or unscrew when filling. I’m not sure why they didn’t go with the usual ¼ turn opening especially with a 2ml tank. There are no seals attached to the top cap underneath. There are two seals on the inside of the tank opening. One in the center that seals around the center airflow tube and a second around the outside perimeter of the opening. The bottom of the tank has the usual branding on it and says DIGIFLAVOR on it.
The kit comes with four coils and four cotton threads which I thought was nice compared to the normal two coils that are included in most tanks. I chose to build with the 316 2.5mm coil since I’m not a big fan of Ni and always prefer 316 coils. I’m sure others will enjoy the included coils.
The build deck is a two post single coil GTA style deck. Once the screws are loosened, it allows you to insert the coil legs in the slots below and then tighten the screws down while holding the coil in place. I’m not going to lie. I struggled a little bit trying to install the coil with just my hands at first and then grabbed my coiling tool which made it much easier to hold the coil in place. I did push the coil legs inward while tightening each one just to make sure they were trapped in place. The cotton threads that were included were a perfect fit. I thinned the tails out quite a bit to make sure I wasn’t over stuffing the holes so it would wick well.
Yes the wicking above is a little messy but I cleaned it up before putting the tank together.
FINAL THOUGHTS:
I have to say that I was rather pleased with the Siren V4 MTL RTA. The redesign was a success in my opinion. I felt like the flavor production was much better than the previous two versions.
Although I didn’t much care for the included drip tips, I could see where the long one would come in handy if you wanted to use it on a side by side device like the Digiflavor Z1 SBS.
I felt like the Siren V4 is a quality designed and built tank that provided good flavor and with all of the different airflow options can fit most vapers whether they want a really tight draw or a loose MTL. I found myself running it about ¾ open since I like a fairly loose MTL draw. I really like the red dot indicator that lets you keep track of where you have the airflow set. The airflow control was tight enough to not let it move accidentally but loose enough to where it isn’t too hard to adjust.
One thing I didn’t really care for was the small tank section that makes it very hard to see the liquid level in the tank. I just got in a habit of removing the top cap to check the liquid level and that seemed to work well enough for me. So, would I recommend the Digiflavor Siren V4 MTL RTA for you? If you don’t mind a 2ml liquid capacity and want a small 22mm rta that provides pretty good flavor and has a versatile airflow control then yes I would.
I’d like to thank Geekvape and Allison for sending the Digiflavor Siren V4 MTL tank for this review and thanks to the readers that keep me doing reviews. Below is a link to the Digiflavor website if you’d like to investigate this product yourself.
