Thanks for checking out my review of the Cthulhu Mjölnir RDA designed in collaboration with Anthony Vapes. In the interest of full disclosure I have been friends with Anthony for a long time now, really good and genuine person along with being one hell of a reviewer. I always try my best to be impartial, I don't work for these vape companies and many have stopped sending me products which I am perfectly fine with. Since this is designed by a friend of mine it makes it tougher but I know Anthony would want me to be as honest as possible which is the only way I would review it.

So Cthulhu....hmmmm, what do we have here
My history with Cthulhu is not great, they come out with nice designs but the quality has always suspect. My favorite product from them in the past was the RTA III, I liked my first one enough that I bought a 2nd. That RTA had it's problems though, one had the AFC ring that would get stuck and I mean bad, almost thought I was screwed with it stuck closed. The other had such a loose JFC that I would sometimes get dry hits as it would easily spin with just a brush from a finger, I could adjust it with my pinky. Overall the quality sucked but I still enjoyed using it. A lot of their former products just did not have the build quality and that always irks me, from shoddy o'rings or grub screws, there was always something that just made me shelf it or give it away.
I was leary of receiving the Mjölnir RDA, what if it has shit grub screws or o'rings that made you want to get a vice grip to remove the top cap? First thing out of the box I put the Mjölnir RDA on a mod to remove the top cap. Came off easily but has just enough grip that you can pick it up by the RDA when on a mod without fear of the top cap coming off and your mod tumbling to the ground...good so far. The grub screws are also good as well and the include spares, (2) hex and (2) slot grub screws, hex grub screws are already installed as well. After 6 to 8 builds the original grub screws are still in excellent shape....hmmm, Cthulhu looks to be upping their game. Even the o'ring for the 810 holds firm but makes it easy to replace your drip tips and every one I tried fit with no problem including TFV style 810's with dual o'rings. So far so good.
The machining on the inside is not the best looking but everything fits as it should. The top cap has some nice machining, no visible burs and the grooves on top and knurling on the bottom are well done, they don't seem to serve a purpose other than style though. I guess you can use the knurling for grip when adjusting the airflow but it is not needed as adjusting the airflow is pretty smooth.
Not as many accessories as you would get from say Geekvape who includes so many extra o'rings you can open up an o'ring store. Still you get what you need along with a 510 drip tip adapter and matching clear 510 drip tip.
The included 810 drip tip is a chubby bastard which reduces the airflow hole to just 7.8mm compared to other 810's with a 10mm opening. It looks nice but it restricts airflow to much for me, I am an airflow ho so pretty much replaced it after a few minutes.
I am guessing the 510 combo is for MTL users or for those that just want a tighter draw. That is the only thing I can think of as to why it is included rather than another 810. I can get pretty close to the draw of a Kayfun or Zenith MTL tanks but I don't know why a MTL vaper would buy this, swing and a miss if that is what they were going for. You can get a pretty tasty restricted draw but I don't personally think it is close enough to a Kayfun to satisfy a MTL'er.
Something different, something borrowed and something blue....oh wait, I think that is for brides? just a new design.
I know I messed up that saying but I am not googling it, I don't care that much. The design of the Mjölnir RDA is definitely something new, I borrowed some pics from Cthulhu's website to better illustrate it.
Here are some pics I took of the inner workings:
Now hopefully it is apparent by the pics of how it works......ahhhhh, that was easy. OK, I will add my 2 cents and how it worked for me, jeez, I never get a break.
Very interesting design, the airflow is angled down and of course redirected to the bottom of the coil. It has openings though so you can drip down the top into the airflow and the juice will fall into the bottom well which holds 1.8ml. I tested this with a syringe and loaded up 2ml which I was able to get completely in there but I could see the juice very close to one of the airflows. 1.8ml is pretty spot on then, just depends on your wicking, too much and you lose some juice capacity. You do have to give the juice some time to get down though, drip like a madman and take a hit right away you bound to wind up with a mouth full of juice and possible leaking. If your going to fill it up then give it 10 to 20 seconds to make it's way down and you will be good.
I do like that the 510 is hybrid safe since I would not even think to use it on my hybrid mechs is it wasn't,
Builds and performance
I tried a bunch of builds from 4mm internal diameter, 3.5mm and 3mm. Various clapton's as well from triple to quad and even 6 core fused claptons. Building was pretty easy, definitely one of the quickest to build on.
I love big single coils so this RDA makes me happy. Don't get me wrong, I am usually a dual coil guy but single coil RDA and RTA's are getting better every year but I usually pass on any that I have to use small coils.
Of all the builds they all performed well and kicked out flavor but the 4mm ID coils restricted the ariflow too much for this guy. 3.5mm and 3mm were both good, my preference was for that 6 core fused clapton 3.5mm ID, love that combo and ohmed out at 0.18 which is what I like on my mechs.
Flavor is pretty damn good, compared to my favorite single coil flavor RDA, the Asmodus C4, it was pretty close. With some juices I preferred the C4 and others it was the Mjölnir but neither dominated the other which is a good thing, the C4 is an excellent RDA and the Mjölnir held its own.
