    Was disappointing using this tank at first with the single coil deck. Juice control was difficult to use as to make it worthless.
    Using the dual coil deck does not suffer the same issues. Once I switched to dual coil deck, the juice control works flawlessly. Would buy again for dual coil use only.

    Not bad but...

    Posted by Unknown on Sep 14, 2016

    Wanted one of these ever since they came out, and jumped on it when Eciggity put it up for clearance at 19.99. Ive been using a single coiled Derringer clone for the last two years and wanted a tank with comparable airflow so I didn't have to constantly redrip. The machining on everything was nice and smooth, no complaints there. The top cap is a bit tough to remove, but after a few fills it gets easier. My main gripe is the worthless juice flow control ring. It just does not work at all once you put the tank back together. I read that there was something about the single coil deck being the problem so I decided to try the dual deck and built my first ever dual coil setup. JFC still didn't move on it, and if you don't get your wicking right, I would top fill it and watch a quarter of the tank pour out the bottom all over the new mod I got for the extra power to push the duals. Ended up trying out the single deck again, this time just leaving out the inner ring on the JFC. Took a few builds to get the wicking right without dry hits after 3 or 4 vapes but I eventually figured it out (cut your wicks so they go about a mm below the wick ring). Without the inner JFC ring, it has no problem top filling while its open as long as you have the wicking done right. Being a huge Lovecraft freak, I really wanted this to be my new #1 but I also wanted it completely functioning as its supposed to. It only lasted about two weeks before I ordered the Tobeco Kayfun 5 from Eciggity, and it was immediately retired. The Kayfun turned out to be like every other Kayfun Ive owned, and got the build perfect on the first try, and with wide open airflow its my perfect vape at 20w. I wanna give the Cthulhu V3 a chance, but Ill wait until it goes down from $40 before I drop any more money on one, especially since its a bigger diameter and will probably overhang on my tiny Sigelei Spark.

    amazing for the price

    Posted by BennyF on Sep 06, 2016

    This tank is amazing for the price. I wanted a cheap cost RTA with a single coil build deck, but I wanted the option to go dual coil if I felt like it. The Cthulhu V2 ticked all the boxes. Plus plenty of extras'. Easy to build on. Everything is tight on it though still need to break it in, struggle to clean because of that.

    easy to build

    Posted by Unknown on Aug 12, 2016

    Bought this version because of the smaller diameter (22 mm) as opposed to the newer version, V3 (26 mm).

    I like how it comes with 2 different decks (single- and dual-coil) so versatility is not an issue. Also, the fact that you can completely take it apart to clean is great.

    My only issue is when you have to refill it...the exterior of the top part that unscrews is smooth so its a little difficult to unscrew if its on there tight. I know this issue was fixed in the V3 version. However, the upside is that it gives the tank a nice, clean look.

    Building the coil is simple and straightforward...look on youtube for help in case you aren't successful by yourself. Flavor and vapor production is really good for 1.0+ ohm vaping, but not massive, thick clouds. However, i don't sub-ohm so i do not know its capabilities of cloud production in that category.

    Overall, very pleased with the product.

    Bury Something Else

    Posted by J. M. on Feb 18, 2016

    So i love RTA's and ordered this for something different and to change it up, to bad all it did was waste money. I was never able to use this tank because the threading on the chimney are all sorts of screwed up along with other parts of the base. I feel like a toddler could have had better luck milling this thing. $34.99 completely down the drain because i wasn't able to use it even once. extremely disappointing.
    This tank is a prime example of one of the biggest disappointments to vaping. everyone is throwing out new products and don't even come close to proper quality control. Vapors buy products and its a complete gamble if you will have an all day every day product or something thats only use is a really ugly paper weight because of course all sales are final.
    Bottom line, save some time by just throwing $35 into your garbage disposal or order something else like the Goliath V2 by Youde or the VCMT by Vaperz Cloud.

    Posted by Unknown on Feb 14, 2016

    Eciggity sent me a replacement dual deck, very smooth process.
    Thanks Vince and Eciggitty!

    Very very pleased with the dual coil deck, whole new flavor level with a SS build.

    Dual deck fail

    Posted by Unknown on Feb 04, 2016

    Love the single deck, the dual deck however came with a stripped set screw hole.
    I ran nickel and SS through the single deck, awesome!
    No spitting, no leaking, choke inducing dry hits are a thing of the past.
    Running this tank on my Treebox TC75, temp control is the real deal.
    Juice flow control works great for me, helps immensely with different ratio juices.
    If it weren't for the dual deck fail 5 of 5.


The Cthulhu v2 is the newest RTA from Cthulhu Mod! It features a velocity style deck with dual airflow or a single airflow deck. 


  • Cthulhu RTA Ⅱ comes with two decks(single coil and dual coil);
