Drew takes the CSMNT RDA for a spin – find out how he got along below… Is this one of THE best RDA tanks of the year? 

Alright guys, I have an RDA to review for you today! All you drippers out there, listen up: this thing is SICK!

About a year ago, I picked up a postless RDA but quickly realized I wanted nothing to do with it. I mean, the thing leaked EVERYWHERE. The center of the deck wasn’t raised up very high and there was almost no room for cotton.

I used that RDA for about a week, but in the end, I just couldn’t deal with the constant mess or/and the ever-present threat of it staining my pockets. And this colored my perception of postless RDAs until, well… about three weeks ago.

And for those wondering which RDA it was (so you don’t end up feeling like you wasted your money the way I did) it’s the MCM underground mod kit.

In addition to the mess this RDA would make when it DID stay closed, the top cap was constantly jarring loose in my pocket. Terrible tolerances are unacceptable in vapes for this reason!!

I was sent the District F5VE and Mystery Mod Co. CSMNT RDA for review and I gotta say it was like a breath of fresh air compared to other postless designs I’ve seen and used.


First off, let’s get a look at some specs:

CSMNT RDA Review – Design 


There are a few features which distinguish the CSMNT RDA from other postless RDA’s. First off, the machining quality is on point. This thing has tight tolerances, holding together when you need it to (in the pocket) and letting you pop the top cap without trying too hard.

The O-rings are nice and fat and this, combined with the tight tolerances, ensures there is ZERO leakage. However, if you place the cotton and coil behind the airflow holes, you will get some drips outside the RDA. Placing the airflow holes so the air goes between the coils is the way to set up this dripper.


The screws are tight on the CSMNT RDA, and the threads have been cut very smooth. This makes for a snug, secure coil fit and ensures that you won’t have to retighten your coils.

Building on the CSMNT RDA is a joke – you just shove the leads in and crank down the grub screws!

CSMNT RDA Review – Performance

When wicking your build, however, you’ll find that you need to put the AFC ring on before cutting the cotton. Cutting it and tucking it with the AFC ring on is the only way to do so; if you do this without it the cotton just pushes between the bottom of the ring and the deck.


Once you do wick it properly, it’s smooth sailing. The grub screws stay snug, and if you keep the AFC on the deck and only remove the top cap, it works pretty well.

The airflow on the CSMNT RDA is great; I feel like it’s the perfect amount. It can be reduced, but the wide-open has yet to disappoint me. The way it rips when the holes are aligned between the coils is PERFECT!!


As for heat dissipation, I haven’t had any burnt lips so far! The drip tip is made of Ultem, which for those of you who don’t know, is the newest craze for drip tip materials. It’s extremely effective at deflecting heat and has a nice feel to it.

The CSMNT retails for $65 over at DirectVapor, and I would recommend grabbing one if you usually run a dripper.

It’s well worth the money, with flavor for days and just the right airflow even on those really hot builds.
