Kizoku Limit MTL RTA Review

It’s not ever day that I get to try random products that I wouldn’t normally buy myself, but whenever it happens, I try to make the best. That was the case with the Kizoku Limit MTL RTA, a rebuildable atomizer from, Kizoku, a manufacturer that I had never even heard of. It turned out that the Limit was the Chinese manufacturer first real vaping product, and considering their lack of experience, it’s actually pretty decent. Let’s check it out:

A Look at the Contents

The Kizoku Limit RTA comes in a small cardboard box with a see-through cutout that offers a clear view of the atomizer inside. Beast a digital representation, and it looks cool too. Anyway, on the back of the box we have some technical specifications and a list of the Limit’s main features, as well as manufacturer information. Confusingly enough the manufacturer is listed as “VapeOnly”, the Shenzen-based company behind such products as the VapeOnly Mind Pro and the now ancient VapeOnly Arcus. From what I can tell, Kizoku is a subsidiary of VapeOnly.

Inside the box, we have the 22mm-diameter Kizoku Limit RTA, a box of spare o-rings and a spare glass section, a mini-screwdriver, some grub screws for the build-deck, organic cotton for wicking, one round wire coil, and a user manual. All in all, a pretty decent starter kit, especially one from an unknown manufacturer.

Design and Build Quality

Before we get into the nitty gritty, you probably noticed that in the opening paragraph I mentioned that the Limit MTL RTA was Kizoku’s first real vaping product. That’s because the Chinese company has some experience in the vaping business, but not really. On its official website, in the products section, there are some chess piece-shaped drip tips, and a magnetic atomizer stand, as well as a new mini mech mod that I hope to show you very soon. That mod and the Limit RTA were launched at the same time, so the company’s previous experience is just in the accessory sector. I only mention that because my review accounts for Kizoku’s lack of experience in product design and production.

The Kizoku Limit MTL RTA measures 22mm in diameter, 56mm tall, and has an e-liquid capacity of up to 3ml. It’s made primarily of SS304 stainless steel, and the machining – from the threading to the fine knurling on certain areas – is actually surprisingly good. I received the gunmetal version of the atomizer for this review, but you can also get it in stainless steel and black.

Starting at the top, we have a classic 510 drip tip with two small o-rings keeping it firmly in place. The drip tip connects to a conical top cap that conceals a clever fill port. The Kizoku Limit features top filling, but it has a truly child-proof cap. I think some adults will have problems figuring it out at first, let alone a child.

To reach the fill port, you first have to grab the knurled top cap and unscrew it all the way. Don’t worry, it won’t fall off, but you will hit a stopper. Then you have to look for the small white arrow on the barrel of the atomizer; that’s the point where you have to push outwards on the top cap, the same way you would on a VooPoo UForce T2 for example, to finally reach the fill port, which also has a silicone membrane to keep the juice from leaking out. After you’re done filling, slide the top cap back into position, and screw it all the way down. Pretty tricky for a child, isn’t it?

The metallic barrel connecting the top section of the atomizer to the bottom one is rather plain, except for a small lightning logo. The glass section is rather small, which is actually one of my cons for this tank, because you can’t see the juice level once you fill past the glass, making overfilling a very likely possibility. The bottom airflow ring features the same type of fine knurling as the top cap, as well as two types of airflow holes.

This thing may be called the Kizoku Limit MTL RTA, as in mouth-to-lung, but it can actually be used in direct lung mode as well, thanks to a massive cyclops style airflow slot that you can use by rotating the airflow ring past the six smaller slots that the atomizer comes set to. It makes the Limit versatile, yes, but don’t for a second think it can match true direct lung RTAs. Firstly, it’s a single coil tank, and it’s not designed for extreme vapor production.

On the inside, the Kizoku Limit is simple and straightforward, at least as far as RTAs go. The top cap and the outer barrel are press-fitted so you won’t be able to take them apart. I’m pretty sure the glass section does come off – otherwise why would they include a spare glass – but I was unable to take it off, and didn’t want to ruin the paint job by using some pliers or a clamp.

The build-deck is small and features a simple two-post design. The openings on the posts are offset, so all you have to do is place the included coil as it is – with the leads pointing opposite ways – and tighten the grub screws. Make sure the coil itself is centered between the posts, right over the small airflow opening. The small round wire coil fill fit just fine, but if you plan on using a larger, more complex coil, space will definitely be an issue.

When wicking, I always cut my cotton leads to the point where they barely reach the wicking slots at the bottom of the build-deck. I just makes sure that they cover the openings completely, to prevent the flooding of the deck with juice, as that would result in gurgling and hot e-liquid spit-back. I also thin my cotton to make it easier for the juice to reach the coil, but some people actually leave it thick, relying on capillary action. To each their own, I say.

One of the things that makes the Kizoku Limit RTA unique is that it has a removable build-deck. That’s right you can simply unscrew it from the base of the atomizer and replace it with a Nautilus coil-head. That’s something I’ve never seen before, to be honest, and while I am not a huge fan of Nautilus coil-heads, I know they are really popular, and suitable for people who don’t want to build their own coils or mess with the wicking.

I much rather prefer using the Kizoku RTA in coil mode, but switching to Nautilus coil-heads is definitely the more convenient option, and it’s nice to know you can opt for either without having to buy another atomizer.

How It Vapes

Kizoku advertises the Limit MTL RTA as an atomizer designed for mouth-to-lung; It’s right their in its name – MTL – and it does live up to that description. I was sceptical at first, especially after seeing that huge cyclops airflow slot, but if you set the airflow to about half of one of those dot slots, you get a super tight draw, just the way I like it. Even with two of those dots, the draw if pretty restrictive, but you can loosen it all the way to six of those slots, and then move to the cyclops slot for a restrictive direct-lung vape.

As I mentioned earlier in this review, the Kizoku Limit doesn’t work as a true direct-lung atomizer – it just doesn’t have enough airflow – but if you get bored of MTL vaping, and have a low-resistance coil that fits on that small build-deck, you can get some decent size vapor clouds out of it as well.

As for the flavor, I would rate it as above average. It’s not the greatest I have ever gotten out of an RTA, but it’s certainly enjoyable enough, provided you get the wicking right. If you’re getting dry hits, or the flavor is muted, trust me, it’s not the tank, you just need to practice your wicking.

As for the flavor with Nautilus coil-heads, I’m really biased against them, to be perfectly honest – I’ve never really liked this style of coil-heads – so I won’t comment on that. You will just have to try them for yourself.

I’ve only been using the Limit MTL RTA for five days, but so far I’ve had no serious issues with it. No leaks, no spit-back, and the coil is still going strong (thanks to an unsweetened, clear juice). All in all, not bad for a tank I had absolutely no expectations from.


The Kizoku Limit MTL RTA is far from the perfect mouth-to-lung atomizer. It has its issues, from the tension of the airflow ring o-rings, which make it tough to adjust the airflow without unscrewing the base, to the rudimentary build-deck, but when it comes to performance, it’s not a bad atty to have in your arsenal. In fact, if you’re in the market for an affordable, easy-to-use MTL RTA, I actually recommend you give it a try. I have a feeling you will be impressed.

The Kizoku Limit MTL RTA was sent to me by Heaven Gifts for the purpose of this review. They currently have in stock for just $34.10.
