Mutation X V4S Black & Silver

Mutation X V4S Intro

The Mutation X line of RDAs by Indulgence are some of the most well known atomizers on the market.  They have always been affordable and with the Mutation X V4, they added bottom airflow to their already popular offset 3×3 side airflow design, making it more versatile than the previous versions.  With the Mutation X V4S, we have the exact same design as the V4, except with a Velocity-style deck.  Let’s see how it compares.

Notable Remarks

Machining/Fit and Finish

Mutation X V4S Taken Apart

The machining is what you would expect from an atomizer in this price range.  Everything fits together nice and snug but there was some hidden machine oil.  I didn’t wash it before building it and man was that a big mistake; the taste of machine oil was so bad that I only took a couple drags before giving it a thorough cleaning.  The machine oil taste did go away completely after giving it a bath in hot water and dish soap.  In my opinion, this is unacceptable; vaping machine oil is extremely unpleasant and every company should be cleaning their products before shipping them to vendors.  The atomizer comes fully assembled; they shouldn’t expect customers to fully disassemble it to thoroughly clean it before the first use.

Another thing to note is the deck o-rings like to fall off when removing the top cap.  Applying juice does make it a bit better but doesn’t fix the problem completely.  Also, within the timeframe of my first build, the plating on the supplied allen wrench chipped off and fell into the juice well; had I not noticed this, I could’ve accidentally inhaled flakes of some mysterious metal.  I’m not sure why the wrench even has a plating on it in the first place.  It’s nice that they supplied a wrench, but at least supply one that won’t be useless after securing the leads down for the first time.

Build Deck

Mutation X V4S Deck

The build deck is what makes this version different from the Mutation X V4; instead of having a split-positive post design, we have a Velocity-style deck with 2.3mm post-holes.  This is definitely an improvement over the previous design.

Ease of Build

Mutation X V4S Deck

Building this is just as easy as any other Velocity-style deck.  It’s one of the best designs out there since the coils are automatically centered and no lead bending is required.  The 2.3mm post holes will allow you put almost anything you can dream of in it, including exotic wire builds.

Juice well

The juice well is 5mm deep and holds a fair amount of juice.  The top of the well sits flush with the bottom airflow ledge which will cause some leaking when condensation builds up on the inside of the top cap.  I will go into this in more detail in the following section.

Airflow and Controller

This is definitely the most interesting part of this atomizer.  It’s similar to the Hatty RDA in it’s ability to provide side and bottom airflow however, where the Hatty fell short, this atomizer succeeds.  You can have top and bottom airflow, bottom airflow only or side airflow only.  There is also a single coil option in all three aforementioned configurations which adds to the overall versatility of this atomizer.

You can turn the sleeve to close off the bottom air holes to your liking or use the included silicon plugs to close them off completely.  To close off the side airflow, turn the airflow controller in which drip tip is attached to.  The only caveat here is that when you close off the bottom airflow using the sleeve, you limit the side airflow options because the side air holes are drilled into the sleeve.

Wide open, there is literally no restriction whatsoever.  Unfortunately, closing everything off still allows some airflow, so mouth-to-lung hits are not possible.  This has to do with a small gap between the airflow controller fins and the sleeve.

Another thing to note is the design of the bottom airflow inlets; they are a flat platform instead of being raised like the Tsunami or the Magma Reborn.  This allows the condensation that builds up inside to leak down those air holes and cause a mess.  Careful dripping will not prevent this since the condensation build up is not really preventable.

Aesthetics

Mutation X V4S Drip Tip

The aesthetics of the V4S is identical to the V4; if you liked the look of that atomizer, you will like the look of this one.  Mine came in black and has a nice sleek appearance.  I also like the two tone look the clear chamber extender creates when installed however, it does make the atomizer look a bit awkward due to how much taller it becomes.

Performance

For the price range, this atomizer performs pretty well.  The flavor was better than I was expecting and the vapor production was just insane.  This atomizer is more suited for the cloud chasers due to the amount of potential airflow but don’t get me wrong, the flavor is certainly above average, especially when using only bottom airflow.

This is definitely an atomizer you want to run hot builds on, preferably 0.3 ohms and lower or series builds with higher resistance coils.  With the airflow set to wide open, it will be enough to cool even the hottest builds.  Using the chamber extender cools the vape even more so.

Likes

  • Good o-ring tolerances
  • Pretty versatile
  • Fantastic vapor production
  • Chamber extender is a nice feature for cloud chasing
  • Nice array of spares

Dislikes

  • Was not cleaned of machine oil in the factory
  • Deck o-rings like to fall off when removing the top cap
  • Closing off all the airflow still allows air to enter the chamber
  • Can be pretty leaky, even when you’re careful about over-dripping.
  • The supplied allen wrench was useless after the first build due to chipping of the plating material

Verdict

Overall, I cannot recommend this atomizer to anyone who isn’t looking for an insane amount of airflow.  If you want an airy draw but not excessively so, great flavor and great vapor production, look into the Tsunami by Geek Vape.  A year ago, the Mutation X was a fantastic atomizer due to it’s performance at this price point but nowadays, there’s a lot of competition in this price range and unfortunately the Mutation X V4S just can’t hang with competition.

My name is Kyle and I have been vaping for almost a year now. I started vaping to kick my 9 year smoking habit and got hooked on trying to get the best flavor out of my atomizers. I am a software developer living in upstate NY and in my free time I like to write shoegaze and dream pop music.

    I honestly love this atomizer for the price. I find MTL possible with the correct resistance single coil, one side of the bottom airflow plugged, the open side turned to either single large hole or two smaller holes (or less) and side airflow closed. That’s a pretty tight draw IMO. I wonder if the gap between the ring and sleeve is bigger in yours than others?

    • Zac, that’s the beauty of vaping, we all see things a little differently and have different opinions. In general, I’m used to a tighter draw; some may say that what I consider to be a restricted lung is actually a MTL draw. When I do MTL, I’m used to a genesis atomizer with a single 1mm – 1.4mm air hole. However, it is very possible that the one I got had larger than usual gaps between the air controller fins. I just know that when I closed every air hole off, I still had too loose of a draw for a comfortable MTL hit. On just about all of my atomizers, when you close the airflow off, there is literally no airflow through the chamber. I hope this clears things up a little.

      • Zac David

        Yes, that makes sense. I have had a longer vaping journey than many, coming on 7 years, and the reason I point that out is only to say that I have used so many different toppers and mods over that time that I’ve come to realize it really is all relative. I remember having to mod cartridges with blue foam and that kind of crap. Obviously, way back then pretty much everything was MTL… really up until not that long ago, I guess. Comparatively, yes, even the lowest airflow settings on the Mutation XV4(S) is still quite open.

        What I meant to say– but didn’t– is that I think this is one of the few RDAs that is capable of doing both MTL or full lung hits (or half/half). In my experience, most RDAs can really only do one or the other. There are a few notable exceptions, certainly.

        Not that I’m trying to convince you of anything. As you say, that’s the beauty of it. Nor is this my favorite RDA. Although it might be my favorite for under twenty bucks.

  • I hate when vaping products still have residual machine oil. It’s overkill, but I give every new vaping product I get 24 minutes in an ultrasonic cleaner filled with warm water and dish soap.
