Ehpro True MTL RTA Review

The True MTL RTA was sent to me for review from Get it here (affiliate). This is a mouth-to-lung tight draw tank designed by the owner of NatureVape out of the U.K. It’s being manufactured and sold through Ehpro.

Not even a year ago it was really hard to find a good MTL tank. Companies just weren’t making them. The only options were tanks that were hard to find or very expensive. Or the Nautilus Mini. But I think with the surging popularity of pod devices, the MTL experience has become a lot more appealing to vapers and now we’re seeing all sorts of MTL tanks on the market for really affordable prices, which I think is great because I’ve always really enjoyed MTL vaping.

There’s nothing that really stands out as far as the design goes although it does have a unique looking drip tip. The designs around the top cap and base look nice too. I’m not a big fan of the look of the top cap and seeing the e-juice fill holes, because it looks like it should have a cover for a cleaner look, but that might not matter much to you.

It’s a very small tank at only 22mm in diameter and 41.5mm tall.

Drip Tip

The True RTA has a removable 510 Delrin drip tip so you can use other tips if you’d like, but the top cap has a raised platform, so it might not look great with all of your drip tips. I know that bothers some people. Personally, I don’t mind.

Something else you should know is that the drip tip itself has o-rings on it, rather than the o-rings being built into the top cap, so you’ll need to use the same style of drip tip if you use your own.

The drip tip has a unique design which I think looks neat, but it can be a little uncomfortable to use. Because of its shape, it forces your lips to go underneath it and touch the top cap. That’s not a problem if you vape at really low wattages and the tank doesn’t get hot, but if you chain vape, it can get warm.

The drip tip is also short so the vape can get a little warm from that too, so again, you might want to use one of your own drip tips instead.

Top Cap / Chimney / Fill Ports

The e-juice fill ports are accessible right on the top of the tank. If you turn the top, it’ll open up the fill ports, so it’s really easy to fill without having to disassemble anything. I’m not a fan of how that looks aesthetically, but I really like the functionality of it. It’s just so easy to fill at any time.

I don’t like the fill ports exposed like that though because it makes it really easy for dirt to get on the seals, which might fall in when you open it up. And you can’t take this apart to clean it out.

The fill ports are a pretty small and they’re even a little hard to fill using fine-tip e-juice bottles, so you might get a little mess filling it up. I would have liked for the fill ports to be a little bigger.

The chimney is short and small, which is also a good thing because it doesn’t leave a lot of space for the flavor to dissipate. So it works well.


The airflow ring moves left and right and stops at each end. This ring also comes off, so you can clean underneath it if you need to. That’s always a nice feature since e-juice always gets behind these things.

There are five different airflow settings you can choose from:

  • 1.8mm
  • 1.6mm
  • 1.4mm
  • 1.2mm
  • 1.0mm

This is strictly a mouth to lung device. In the wide-open setting, it’s an airy restricted draw and at the smallest setting, the draw is very tight.


The deck is small, so you’re somewhat restricted in the size of coils you can use, but this is a single-coil MTL tank, so it doesn’t make sense to try to fit large coils in here anyway. I’d say it’s got just the right amount of space to build a coil that this tank is designed to run. For reference, the coils included in the box are Clapton coils, 5 wraps, 2.5mm inner diameter, and come out to 0.916 ohms (on the Smok Alien).

The True tank has a clamp system to hold in the coil. There are two posts with Phillips head screws, each with their own clamp. When you raise a screw, the clamp loosens. They aren’t spring-loaded, so they aren’t as easy to use as other clamp-systems.

A feature that Ehpro points out is that you can tighten your coil down either beneath the clamp or between the screw and clamp, so whatever you prefer. Ehpro recommends that you use Clapton coils under the screw and basic round wire builds under the clamp.

This is a bottom airflow tank with wicking channels off to the side. With tanks like these, wicking can always be a challenge because you have to make sure you use enough cotton to fill the holes to prevent leaking, but also not too much that you restrict the cotton’s ability to wick properly.

I’ve found that cutting the wicks at the point where they are just outside the edges of the base is just about perfect. Basically, you just want the wick ends to reach the bottom of the wicking channels. I’ve also found that it’s fine for the wicks to come out a little from the bottom. It’ll still wick very well.


The tank works great. I haven’t had any problems with leaking. It doesn’t gurgle at all. And the flavor is really good. I’m actually really impressed with the flavor, even when using 50mg salt Nic e-juice, which tends to be a little muted due to the high-nic.

This tank is a great MTL tank and I think people who like mouth to lung vaping. I even think this is a great alternative to pod vapes just because it can work just like one.

Final Thoughts

I’m not a fan of the looks of the exposed fill ports and I also don’t like how small the fill ports are. I’m not a fan of the style of the drip tip either. And I would have liked to see spring-loaded clamps on the deck.

As for pros, I like the looks of the tank, I like having all the different airflow sizes to find the perfect draw for my preferences, and the best and most important feature, the flavor is very good.

I was sent the True MTL RTA for review from and you can get it from them for $32.40 (affiliate).
