I really like the design of this tank. I’ve never been a fan of the way bubble tanks look, but Geek Vape made this one look pretty good. I think what makes it look better than others is the shape of the top cap and the base. The mouthpiece has this slant that leads into the tank, rather than being boxy and straight. But these angles create more of a roundness, so the size of bubble glass seems more subtle. And the base of the tank does the same thing, leading up into the tank at an angle.

As for the rest of the design, everything looks good. The finish for all of the colors look nice and I also like the low-profile style of the drip tip. On the chimney, you’ll see this very finely printed design of Zeus, the Greek god. That’s really cool. It’s a very nicely designed RTA as far as style goes.

It’s 25mm in diameter and it stands about 1.8 inches tall.

Drip Tip

The drip tip is a very short low profile tip. You also get an extra Ultem 810 drip tip in the box if you want something a little longer.

And of course, you can use your own on here too. And if you want to use a 510, there’s a 510 adapter in the box too.

Top Cap, Fill Ports and Airflow Control

The top cap unscrews from the top of the chimney-piece, right above the airflow control. There’s nothing interesting about it.

When you take that off, you get access to the fill ports.

This is a top airflow tank, so that should help prevent leaks. On the top cap is the airflow control ring, which comes off so it’s nice that you can remove it and clean behind it. The one problem with it though is that it’s just a little too loose and comes off really easily. But as far as adjusting it goes, it moves nice and smoothly both ways and comes to a stop at each end.

And of course, you have the silica glass tube, which is 4.5ml in the standard version. The 4.5ml glass is pre-installed, but you get a 3.5ml straight glass tube in the box if you want to use that instead. And I know some people really hate the way bubble glass looks, so it’s nice that you have the option to switch it up if you want.


The chimney on here is a double-chimney, which Geek Vape says creates optimal flavor.

The top chimney’s chamber covers the internal airflow chamber. That internal chamber is held inside of the outer chamber with an o-ring.

When putting this back in, you have to make sure that it’s lined up correctly. If you look inside the outer chamber, you’ll see the slots where the inner chamber is supposed to slide in.

You’ll also notice that this inner chamber has airflow holes. So when you take a hit from the tank, the airflow comes in from the airflow at the top, goes between the two walls, and is directed straight to the coils. It’s a really cool idea. The airflow on the Zeus X is super smooth, and I think this is one of the reasons. I also think this is helping with flavor production.

Build Deck

The Zeus X supports both single and dual coil builds, but the one thing you have to keep in mind when doing single coil is that you need enough cotton to fill the wicking holes so that it doesn’t flood. That means you need to build a pretty big coil. GeekVape recommends a minimum of a 3mm coil or bigger.

It’s a postless deck, so you need to cut the coils to the right length, drop them down into the post holes and tighten it all down with the pre-installed flathead screws.

I’m not really a big fan of postless decks because I can never get the coil legs snipped to the right length. I don’t have one of those coil measuring tools, but I should really get one. What do you all think about postless decks? Do you like them or hate them?

Anyway, there’s some space at the bottom of the posts that would make you think it would be easier to clip the leads once the coils are in, but that space is way too small to get the wire clippers in there. So you really do need to try to get the measurements right when you clip the leads before installing them.

When aligning the coils, you’ll want to make sure they don’t go past the edge of the posts.

The chamber isn’t very big, so that’s about as far as you want to go to prevent the coils from touching the chamber and shorting out.

The posts sit a little tall, so when you wick the coils, you’ll want to cut them just a little longer than the outside of the base. Then you just tuck that into the holes and do the other side.

Geek Vape does include two Ni80 0.4ohm Coil and some cotton, so you have what you need to get started.

Flavor & Performance

The flavor is pretty good. It’s not as good as a mesh tank, but to compare to other RTAs that I’ve used, this one is up there with the best of them.

The airflow is nice and smooth. With the airflow wide open, it feels good and you get a lot of air coming through. The flavor is good wide open, but it gets better the more you shut it down.

Final Thoughts

So that’s it for the Geek Vape Zeus X RTA. It looks good, the top cap is easy to take off to fill the tank, and the double-chimney airflow creates some really good flavor. The postless deck makes installing coils a little more challenging, but it’s not really a big deal. So yeah, I really like this one a lot.

EXvape Expromizer V4 RTA Review

The Expromizer V4 was sent to me for review from You can get it here (affiliate). This is a tight-draw tank from EXvape and it’s designed in Germany and made in China.

I’ve never used any of the previous versions of the Expromizer, but I did watch Todd’s Reviews take on the V3 just to get an idea of what might have changed. The V3 had bottom airflow, a lot of parts, a juice flow control, and 4ml extension parts. Nothing bad, but definitely more complicated than your average tank. The V3 was able to do restricted lung hits, so it had quite a bit of airflow. Todd was also vaping it around 26 watts. The max coil size was about 2.5mm inner diameter, and maybe 3mm with a basic round wire build. The juice flow control wasn’t visible from the windows, which was poorly thought out, but other than that it was machined very well. He said the flavor was very good too. One of Todd’s complaints on the V3 was that the airflow hole beneath the coil was too big at 2.6mm diameter. He said it still worked well, but he felt that the draw would be better with a smaller airflow hole under the coil.

Ok, so we know a little about the previous version so let’s see what’s new.


  • 2ml Capacity
  • Optional 4ml version with Bubble Glass
  • Optional 4ml extension straight glass
  • 23mm diameter, 43mm tall or 56mm w/drip tip, 76g in weight
  • Stainless steel
  • Top Airflow
  • Colors: Brushed steel, Polished Steel, Black
  • $44.90 from

In The Box:

  • Expromizer V4 tank
  • Yellowish tinted acrylic tank (pre-installed)
  • Spare clear glass tank
  • Yellowish tinted mouthpiece (pre-installed)
  • Black delrin mouthpiece
  • Screwdriver
  • Spare o-rings
  • M2 srews
  • User manual


The Expromizer V4 looks great. In my mind, this really looks like a high-class German-designed product. Even if it’s made in China, it definitely has that German-inspired look and quality to it. It’s a nice piece of gear.


The tank comes with the 2ml yellowish tinted acrylic plastic tube pre-installed. You also get a spare clear pyrex glass tube in the box.

There are also optional tanks that you can buy.

There’s a 4ml pyrex bubble glass tube, which is the same height as the 2ml glass, but it’s 27mm in diameter.

Then you have the 4ml extension kit. This is a taller tube but it’s 23mm in diameter, so you get more e-juice capacity but it’s still flush with the base. And there are two versions of the extension kit; one is the yellowish acrylic tank and the other is a clear pyrex tank.


The mouthpiece on the Expromizer V4 is two pieces. You have the metal piece that fits snugly into the top cap and then you have the plastic tips that screw onto the top of that.

Exvape included both a yellowish tip and a black Delrin tip, so you can customize the look a little bit.

The hole in the tip is really small and matches up with the hole in the chimney piece so it’s lined up perfectly all the way through.

Airflow Control

The V4 has top airflow, designed to prevent leakage and according to Exvape, to appeal more to beginners. This is using top-to-bottom airflow, which is a familiar airflow system that has become popular with a lot of the newer top airflow tanks. The way this works is that it pulls in air from the top of the tank, transfers it down the sides of the inside of the chamber, and then it pulls it back up from the beneath the coil and through the chimney. It works really well and the flavor comes out pretty well.

The airflow control ring comes off so you can clean behind it, which is always nice. There are six settings to pick from. Each hole is 1mm in diameter, so you can really get a nice tight draw if you want. With all airflow holes open it’s still a very tight draw. You can’t get a restricted lung draw on this tank. So the V4 is really designed for those of you out there who want a tight draw. At the lowest airflow setting, this is one of the tightest draws I’ve ever had on a tank.

And the draw is super-smooth and just feels great. I really like it.

Liquid Control

The Liquid Control system is a mainstay of the Expromizer family of tanks and it’s back in the V4. You’ll see it inside the bottom of the inside of the tank. You change settings by turning the base of the tank. You need to do this while it’s attached to a device because it has to turn in the same direction you tighten it onto the device. That also means that the tank can get get a little tight on the device. Not really tight, but just a little tighter than usual. So because of that, when taking the tank off, you want to grip it by the base, not the glass, or you’ll end up unscrewing the glass.

The Exvape site says there are five settings to pick from, but I only see three. There are three holes on each side and both sides have to be open. You can’t just close off one side. So yeah, seems like three options to me. Anyway, these are designed to let you control how much e-juice you want to allow into the deck. The smallest holes are 1.4mm and the biggest holes are 2mm. The middle hole is probably right between that.

This is a great feature because it lets you adjust the settings to your build. If you’ve used many rebuildable tanks, you know that different types of coils, differences sizes and inner diameters of coils, and even different lengths of cotton can change the way the tank works. So if one build works great and then you switch it out later and it doesn’t wick as well or if it wicks too much and gets flooded, you have the option to change the e-liquid control.

Another cool reason to use this is that you can use any type of e-juice in here. Exvape says that with thin e-juice, like high PG e-juice, you want to set the control to the smallest Liquid Control setting. For thick high-VG e-juice, you open it wide up to the largest setting.

On older models of the Expromizer, the cotton sat above liquid wicking holes. The cotton had to cover the holes to prevent it from flooding. That also meant that only the tips of the cotton would wick e-juice. This actually worked well from what I’ve heard, but Exvape wanted to make it even better in the V4.

So the V4 now puts the cotton in direct contact with the e-liquid, which is supposed to provide even better liquid flow. I don’t have any older models to compare, but the Liquid Control works great. It wicks great, all the time.

Top Fill Top Cap

The Expromizer V4 is a top-fill tank. The key thing to remember with this tank is that it has that liquid control setting built in, which means that you need to remember to close it off before filling it up or you’ll flood the tank. So to fill it up, just close the liquid control, screw off the top cap, and that’s it. There’s a lot of space here so you shouldn’t have problems with using any size of e-juice bottle.

Just remember to open up that liquid control again before vaping.

The Build Deck

Like all previous versions of the Expromizer, the V4 is a single-coil deck. The coils sit in the middle and with the coil lets going in both directions, you just tighten the legs down under the Phillips head post screws. The screws are flat on the bottom, but the coil legs still try to work themselves out so you’ll need to make sure they’re really pinched in there.

You’ll also notice these little ledges sticking out. Exvape doesn’t say if these have a purpose, but they’re useful for wrapping the wire under and tightening the legs down. My guess is that’s their purpose.

When trimming the coil legs, you need them to be absolutely flush with the posts. If they stick out even a little, you’ll get friction trying to screw the chimney back on.

The tank doesn’t come with any cotton or coils or any recommendations for sizes, so you’ll have to play around with it. If you’re going to use Claptons, a 2.5mm diameter coil is about as big as you want to go. You might be able to fit 3mm diameter, but it would probably be best to use basic round wire builds if you go that high. And 3.5 is just too big. 2.5mm diameter really seems like the best size for this tank.

When wicking the coil, you want to cut the cotton so that it just reaches the bottom of the deck and maybe even a little less. I’ve found that if you put too much cotton in there, it plugs up the Liquid Control holes and when you take a hit, it just sucks up a ton of e-juice into the deck and it floods like crazy. And there’s no way to correct it after that other than by taking it apart and cutting some of the length off of the cotton. Just make sure you aren’t plugging up those liquid control holes. Other than that, the Liquid Control feature works great and it just wicks up e-juice like nothing.

Final Thoughts

With a rebuildable deck and the Liquid Control, this will probably cater more to advanced vapers, but it’s really not all that complicated to use. Based on what I’ve seen of the V3, Exvape fixed pretty much all of the previous flaws. You can see the Liquid Control while you’re setting it, and the draw is perfectly designed for tight draws. It still has great wicking and the flavor is really good. My only cons would be that the post screws try to push out the coil legs and that you have to be careful how you wick it so that it doesn’t flood. But in the end, this is a really awesome MTL device. The best MTL tank I think I’ve ever used as far as flavor and performance goes actually, so in my opinion, this is a must-buy.

Smok Nord Review

The Smok Nord was sent to me for review from This is a really cool looking pod device from Smok that you would think is designed for tight-draw vaping, but it isn’t!


  • 1100mAh battery
  • 3ml capacity
  • Wattage: 10-15 watts
  • Size: 94mm tall, 30mm wide, 18.8mm thick, 80grams in weight
  • 13 colors
  • $26.90

In The Box:

  • Nord device w/pod
  • 0.6 ohm mesh coil
  • 1.4 ohm regular coil
  • USB cable
  • User manual


Smok always does a really good job with their designs. There have been some bad ones here and there, but for the most part, I think their products look really good. And the Nord looks nice and modern to me. You can get the Nord in just about any color you’d like. They have seven versions of the resin design and six versions of the solid colored snakeskin pattern.

And this little thing has some heft to it. I wasn’t expecting it to be as heavy as it is. It’s not so heavy that it’s bad or anything like that. It actually makes the Nord feel durable and higher quality.


The mouthpiece has a duck-bill design, which is comfortable to use. And the airflow hole in the mouthpiece is fairly big, so you can get plenty of airflow through here.


Some people like draw-activated and some like button-activated. I like both and I think there are pros and cons to both. But this one is button-activated for you button lovers out there.

Five clicks turns it on and five clicks turns it off. So that’s a nice feature for anyone who likes to make sure their devices are off before throwing them in a bag or something.

The button has a nice sharp click to it. Just hold it down to take a hit.


Instead of the pod being one single piece that you use and throw away, you reuse the pod but replace the coils that go inside of it. So technically I guess this isn’t a pod system. It’s a tank system that looks like a pod system. But I’m still gonna call it a pod system 😉

So you get one pod in the kit and two replacement coils. I really like that Smok designed the pod this way. It’s much less waste and it makes buying coils more affordable.

There are two sizes of pods available depending on where you live. For people in the EU dealing with TPD restrictions, there’s a 2ml pod and for everyone else, there’s a 3ml pod. For a device of this size, a 3ml tank seems perfect just to keep the overall size to a minimum, but if you’re vaping the mesh coils with low-nicotine, you can get through 3ml’s pretty quick.

To fill it up, there’s a little rubber plug on the side. Pop it out and fill it up. Make sure the plug is in tight and then drop it into the device. On a new coil, you’ll want to wait a few minutes to let the liquid soak in before taking a hit.

There’s also this e-liquid window so that you can see how much liquid is in the tank.

The little window is okay, but I think they should have put a little more thought into it. You can only see the liquid when it’s all the way full. Yeah, you can tilt it on its side or upside down, but it’s still a little hard to tell how much liquid is in there. It’s not a big deal because you can pull the pod out if you really want to see inside, but I think if they’re going to include a liquid window, it should be more useful.

I have noticed that there’s a little bit of leaking with the pod. After finishing up a tank, I’ll pull the pod out and find e-juice all over the inside of the device. It’s not pouring out or anything, but you will want to wipe it down.

Coil Heads

Smok makes four different coil heads for the Nord.

One is the Nord Mesh, which is a 0.6-ohm mesh coil. This coil comes with the kit. This one is designed for big hits and flavor, so you won’t be using high-nicotine e-liquid with this one. That mesh also makes it fire fast. It’s perfect for sub-ohm vaping. This coil head has a max wattage of 25 watts, but the device can only push a max of 15 watts, so that’s what you’ll get. But man, you can get some clouds through this coil head. It’s almost like using a high-wattage device. It’s crazy. And the flavor is very good out of this coil head.

The other coil that comes with the kit is the Nord regular coil, which is a 1.4-ohm coil head with a maximum wattage of 12 watts. This one decreases the wattage and reduces the airflow. So this one is for people looking for a tighter draw or for people using high levels of nicotine, although I don’t think the draw is tight enough for mouth-to-lung hits. It’s more of a restricted lung hit. The flavor also isn’t all that great. It’s okay, but nothing compared to the 0.6-ohm mesh coil.

And there are two other coil heads that you can buy that don’t come in the kit. One is a 0.8-ohm mesh coil. So this one is somewhere in the middle of the other two coils. It’s designed for bigger Mouth To Lung hits and for more flavor than the regular coil. The max wattage of that coil head is 16 watts, so you’ll be getting the max power that the Nord can give you, which is 15 watts.

The other optional coil is the 1.4-ohm ceramic coil. I didn’t get one to try, so I can’t say much about it, but it probably has better flavor than the regular coil, but not as good of flavor as the mesh coil. And it probably lasts longer than the regular coil too. Since it’s a 1.4-ohm coil head, basic ohms law tells us that is also has a max wattage of 12 watts.

The coils need to go in a certain way, which is easy to figure out. The flat sides match up to the flat sides on the pod. It’s press-fit, so you just push it in and you’re good to go.


The Nord has an internal 1100mAh battery installed, which is a pretty big battery for a pod device. Battery life will depend on what you’re running through it, of course. If you’re running high-nicotine and vaping less throughout the day, you could probably go a few days without charging it. If you vape low nicotine or zero nicotine and you’re just taking hit after hit, you might have to charge it after 1-2 days. But either way, that’s a big battery for a pod device.

To charge it, you plug the micro USB cable into the bottom of the device and you can vape the Nord while it’s charging, which is always nice.

The LED light on the device also indicates battery life; red is less than 30% battery life, orange is between 30-70%, and green is between 70-100% charge. You can do two clicks on the button to quickly see what the battery charge is.

Safety Protections

  • Short circuit
  • 8 second cutoff
  • Low voltage protection

Airflow, Performance, and Flavor

The airflow depends on the pod that you use, but even with the 1.4-ohm coil head, it’s a loose draw. So if you like really tight draws, you can’t get that here. I personally like really tight draw on pod style devices, so in my opinion, I don’t think this will satisfy vapers who like mouth To lung hits.

With the 0.6 ohm coil, you get a big loose and flavorful lung hit. This almost works like a box mod but packed into the small size of a pod device. This is where this device really shines. So if you like loose airflow, big clouds, and lots of flavor, this is the coil you’ll want.

Final Thoughts

So that’s it for the Smok Nord. This isn’t a tight draw device like you’d think just by looking at it. This is designed for big clouds and big flavor, in a tiny setup. The flavor is great on the mesh coils, it’s nice and small, and it’s easy to use. I really like this thing.

I got this from, so if the Nord sounds like something you’re interested in, you can get it from them for $26.90 (affiliate).
