Drip Tip
Some people like Ultem and some people don’t. I love the way it looks and I like its resistance to heat, so I’m a fan of it on this tank. I also think it really makes the stainless steel look good.
But other than that, it’s a typical 810 drip tip.
One thing I would have liked for Ehpro to include would have been a 510 drip tip adaptor, especially since the chimney is about the size of 510.
Top Cap and Chimney
The drip tip fits snug into the top cap with the o-rings embedded into the top cap. So you can use any 810 mouthpieces in here. You might notice though that the although the drip tip has an 810 bore, the hole in the top cap is much smaller. So the drip tip is more for comfort, rather than function.
The threads on the top cap are pretty nice. It unscrews smoothly and I haven’t had any issues with it getting overtightened. So it’s been nice.
The fill ports are nice and big here too.
There’s really nothing special about the chimney section so I don’t have much to say about that.
The Glass Tubes
There are two glass tubes included in the box. The straight glass tube holds 3.5ml of e-juice and the bubble glass holds 5.0ml of e-juice. The glass fits between the top cap and the deck very nicely. The seal at the top cap holds it very secure and it seats deep enough into the deck so that it doesn’t have any issues with sealing to prevent leaks.
The Deck
The deck is gold-plated which they say creates perfect electrical conductivity. I don’t know if something like that even matters for a single-coil RTA, but yeah sure, gold plating is good for conductivity.
What’s interesting about this deck is that although it’s a single coil deck, there are four posts. That means no matter which direction your coils are wrapped, you don’t have to worry about fiddling around with them to get them to fit. That makes installing coils in this RTA a little easier.
The way they designed the posts requires that you fully remove the screws to get the coils in, or at least one of the screws. I’m really not a fan of that at all. Not only does that require extra work, but it also makes it a lot easier to lose a screw. But once you get those coils in there and the screws tightened down, all you need to do is clip the leads from the back and wick it.
One other thing I found is that one of my screws was stripped. It just wouldn’t tighten all the way down. The accessories bag has four other screws in there, so that’s good at least. All of the other screws were fine, but even still, the screws or the threading on the posts just don’t seem to be machined very well. The screws go in a little crunchy.
The coils they included in the box are built at 0.27 ohms and are tri-core fused Claptons.
On the Ehpro website, they claim that these are quad cores built at with 28g NI80 cores with a 38g NI80 wrap, but I took two of the coils apart and they are definitely triple-core, not quad.
If you really like the included coils, the wire gauges are probably what EHpro claims or at least close to it, so you can try to recreate them with those specs.
So that might give you an idea of what you can expect to fit in here. I’ve also tried other sizes of coils in here too. A 3.5mm inner diameter basic round wire build pushes the limits of the maximum height before the coil will short on the top of the chimney. I would say stick with a 3.5mm diameter or smaller coil.
I actually did some measurements of the chimney and I’ve found that you get somewhere around 4-7mm of space above the airflow hole in the middle of the deck, but you start to lose space as that chimney closes in. I’d say that once your coil goes 1-2mm above the posts, you’ll get close to shorting out on the chimney.
I found that wicking is easy with a little experimentation, but it might take you a few tries in the beginning. I found that cutting the wicks just a little past the edge of the deck is just about perfect.
You’ll want the wick to be thick enough to fill the wicking channels once the barrel is on, but not so tight that they can’t wick well. You also want to make sure that the wicks aren’t too thin, or you might get leaking.
Airflow
This is a bottom airflow tank, which comes in from the sides of the tank and comes up directly beneath the coil and up the chimney. It seems to work pretty good for flavor. I’ll talk more about that soon.
So the two airflow slots are very big but don’t let that fool you. This doesn’t have a ton of airflow. It has good airflow, but nothing crazy.
With the airflow slots wide open you get a slightly restricted lung draw. This isn’t an MTL tank, so it’s not really tight by any means, but you can’t just breathe through this thing. As you close the airflow down, it gets increasingly louder. It’s not so bad that it really bothers me, but yeah, it can be a little loud.
Performance and Flavor
Okay, so I’ve tried several different builds in this tank and the flavor was just okay in my first couple of builds. But then I gave the included triple-core Clapton another try. I got the wicks just right and I was able to hit it at 50-60 watts and it was at that point that this tank became a true flavor-chaser. I really think it comes down to proper wicking. For my personal preferences, I found that once I get this running well at 50 or more watts, I get a whole lot of flavor out of it.
Accessories
I really like all of the accessories that they included. They give you everything you need to get this set up to use right out of the box. Most companies don’t do that. A pad of cotton and three coils will go a long way here. So I like that a lot.
Overall Thoughts
It’s a good RTA but it has its pros and cons. The flavor is very good if you get it built right and I also really like the way it looks. The airflow is also very nice for a single-coil tank. It really doesn’t need to be any more open. As for the cons, I don’t like the threading on the posts, I don’t like having to remove the screws to get a coil in, and I wish they included a 510 adaptor. But overall, it’s a pretty nice RTA that has great flavor.
So if that sounds like something you’re interested in, you can get it from BuyBest.com for about $22. Not a bad deal at all.
