Geekvape Ammit MTL RTA Review

This was my second ever rebuildable, and it says something about what I think about it that it is still in regular rotation. This came out in 2018 where it seemed like every manufacturer was trying their hand at a MTL RTA. The Ammit does a couple of things differently to the majority, and as I’m a sucker for the unusual, I was keen to try it out.

Build Quality & Design

Working down from top to bottom, the first thing you’re going to notice is the drip tip.

The way Geekvape have done this is, is with a screw in black delrin tip on top of a nice chunky bit of metal with a 510 connector. This means you have the option of the two tips that come with it (2mm and 3mm bore I believe), or alternatively you can pull out the whole section, and use whatever 510 drip tip you like. I actually really like this set up, and I think it looks better with the stock tips, they have a nice vase shaped profile and quite a sharp edge to them. However no matter how I was vaping, or which tip I used, I always seemed to get some condensation in there and it would end up sitting right near the tip. So it was a no from me on either of the included tips, and I switched out to my favourite Nautilus 2 stainless steel tip that I tend to prefer for MTL vaping.

Moving down the tank the next thing we get to is the top cap and fill ports.

This is a pretty standard top fill system, two nice big holes to put your e-liquid in, which are accessed by unscrewing the top cap. This was before bayonet caps started getting more popular, and I quite like avoiding the over-engineering you tend to find on flip or push systems, not to mention that those seem far more likely to leak all over me if I’m carrying it in a pocket! It’s quite a lot of screwing you need to do to open it however, somewhere around three full rotations to take the top off. Having said that, it means that it’s not going to unscrew itself accidentally, and the detail on the sides means it’s easy to get a good grip to do so. The threading on this is super smooth, and you have an o-ring actually set into the top cap. Not sure what this will mean if/when it ever starts to perish, but I think it should be easy to jury rig something as there’s a nice channel that it sits inside of.

Next up we have the airflow control, yup, this tank has the AFC at the top of the tank, with the air coming down inside the double walled chimney section, and then getting fed up onto the deck for the 3D airflow (more on that in a minute). Unfortunately for me, this is where we run into my first quibble with this tank. The airflow has plenty of options, with 5 holes in decreasing sizes, and you have the option of either a single selector hole, or a cyclops style to open up several at a time. With the airflow fully open you can just about manage a decent slightly restricted lung hit on this, and closed right down to the smallest, it is TIGHT, in fact it reminds me very much of the original Nautilus on it’s second smallest hole. Now I tend to vape it on either the smallest or second smallest hole, but if you have it wide open it makes a lot of noise due to the way the air is travelling down inside the chimney. Very much a windy sounding vape here. Happily when you’re not feeding that much air in, it’s not too bad, although it’s not going to be as quiet as some tanks where the air isn’t travelling quite so far. So it’s got some plus points in it’s flexibility, and importantly for me it manages a really nice tight MTL draw, however changing between the settings is hard work. I’m not sure what it is, but the AFC is really stiff on my one of these, there’s no o-rings to grease up here as it’s straight metal on metal, and you can remove the AFC control ring for cleaning (always nice when a tank splits into lots of pieces). I think the way the top cap screws down onto it doesn’t help matters, as it just adds another point of friction, but even taking the top cap off you really need to twist this hard to change your selection. Now this isn’t something that I’ve heard other people complain about, so it may just be my tank is a little off, and to it’s credit, it does mean you’re not going to be constantly having to reset your airflow because you accidentally knocked it. The other advantage of having top airflow, is that it’s pretty much leak proof. I’ve run this atomiser for months, and I have never had any juice leaking out of the airflow.

The tank section is either 4ml on the international, or 2ml on the TPD, I’m not sure but I’ve heard the TPD one is just using a silicon bung to reduce the capacity, so I presume it would be easy to remove. As with most of my tanks, I much prefer the 4ml capacity as means you can be vaping all day and not have to think about refilling. One thing I noticed with mine is that when I dissembled it, the glass section seemed almost welded to one of the o-rings (you get orange and clear in the packaging) and it took a little bit of work to get it to come lose. I’m not sure what caused this, and I haven’t had the problem since, so it may just be that it was sitting dry for a relatively long time/got hot. The o-rings also seem relatively small, and when I remove the deck section I have about a 50/50 whether the bottom o-ring is going to stay on the deck, or come up with the glass. Not a major thing, but I wish I had some more clear o-rings to see if a new one sorts it (I’m not keen on the garish orange!).

The deck is a raised deck with two vertical posts with small cross head screws and holes in the posts to push your wire through. You’ve got a couple of smallish wicking holes, and the 3D airflow that I mentioned earlier. The way this works is that the air is coming down inside the double walled chimney, and then it’s funnelled straight up under the coil, but also from either side via angled air holes, one between the posts and the other sticking up on the other side. This seems to do a decent job but there’s a couple of points to note about building on this. Firstly the wicking holes are relatively small, and if you have a lot of cotton from a chunky coil on here it’s very easy to totally clog them up. With a simple round wire build at 2mm internal diameter, I don’t really need to thin down the cotton, but anything above this and I will gently need to pull some out. Simple rule of thumb is that if you start feeling like you’re having to really push it into the holes, you have too much cotton. Also, because the deck has a raised lip around it, it’s fairly challenging to actually see these, I would definitely recommend using angled tweezers to help. The other two things that make building on this a tiny bit more challenging than normal is that not only are the holes for your wire pretty tiny in the posts, limiting the choice of coils you can fit. But also that the air hole that sticks up means that you can’t easily the build the way I normally would on this sort of deck, having the legs fairly long and sliding them in horizontally, as the air hole means that your coil will bump up against it. Now this isn’t too much of a problem if you’re using thin wires, but it is something to consider.

The base of the tank is fairly short as the AFC is up top, but fairly wide at 24mm. It feels like a nice solid lump in your hand.

How does the Geekvape Ammit MTL RTA perform?

I’m really pleased with the flavour on this tank, in my preferred MTL mode with a really restrictive airflow, it provides a nice clean flavour. I tend to prefer the flavours that have higher notes, especially with some menthol/coolada added in to the mix, and that’s where this tank really shines. It allows you to get a lovely cool hit, whilst still having enough middle ground for berries and fruits to make themselves known. I’ve found that it’s not that good on the darker, more complex flavours, tobaccos and custards. Everything just seems to get a bit mushy and you can’t separate out the different flavours.

Opening up the airflow it’s still decently flavourful, but I think you get much better flavour from it with a tighter draw. This is often the way with tanks that try to do both MTL and DTL, it’s really hard to make a tank that can handle both of these well. It almost always seems to be the case that if you get one right, it takes away from the other. This is one of the reasons that I much prefer it when a manufacturer knows what it’s aiming for and commits to it. If you buy one of these tanks that’s tries to do both, it’s really hard to know ahead of time whether it’s going to lean one way or the other. So with the Ammit I would say it’s primarily a MTL tank, that can also handle a bit of DTL if you fancy changing things up for a bit.

Final Review Verdict

This is still one of my standard tanks, and is in frequent rotation. It’s currently sat on my SVD 2.0 with a 2 ohm coil in there, vaping at about 11W, and personally I love the match up of the knurling on the tank and the mod. But I’ve also run this on more powerful mods with something like a 0.4 coil in there, and it handles both of these styles with aplomb. It definitely has it’s downsides, the AFC ring is probably my biggest bugbear. But all in all, it’s one of my standard tanks for all day vaping, not when I’m trying out new and interesting liquids, but filled with my standard iced berries, the capacity, no leaking, the build quality, and flavour profile make this a winner.


It has some niggles, but for a relatively inexpensive MTL RTA, it’s the sort of tank that if I ever broke it, I definitely would buy it again.
