The Profile was quite possibly the RDA with the largest impact in 2018. It brought rebuildable mesh atomizers back in existence, and topped almost every best RDA list due to its innovative design and great performance. Now Wotofo cooperates once again with Mr.JustRight1 for the second RDA in the Profile line, the Profile 1.5. It is a 24 mm squonk-first RDA, with a series of updates that range from minor to significant.
So, did the world need a 1.5 version of the Profile RDA? Keep reading to find out.
Price: $34.99 (at Wotofo)
Colors: Black, gunmetal, ss, blue, gold, rainbow
Looking at the RDA fully assembled, outside of the airflow, not much seems to have changed from the first version. The small gap between the airflow control cap and the chamber cap has been removed, making the 1.5 version appx. one mm shorter, and the logo looks a bit more cartoony now. But until you remove the top cap, the two atomizers look really similar to each other.
Once the top cap is off, the differences between the two build decks are obvious. The 1.5 edition comes with a much larger deck and overall space, and the way they accomplished that is by making the top cap significantly thinner. The juice well is also shallower now, and the two deck O-rings of the original have been replaced by a single thicker one. As a result, the top cap of the 1.5 can be removed much easier this time around. But make sure you lube everything up with some VG for even better results.
I like the fact that Wotofo decided to include a low-profile drip tip as a second option. I am not the biggest fan of these drip tips as my lips often end up touching the top cap—which for some reason always happens after I have been chain-vaping for a while. But I know some people love them, and having options is much better than having one more of the same.
Overall build quality and machining are really good, and I have no complaints whatsoever on that front. The only minor issue is that the gap of the locking mechanism on the deck is a tiny bit too long, which means that the top cap feels a bit wobbly laterally. But that’s is a nitpicky con and most people won’t even notice it.

The larger size of the deck on the 1.5 edition makes it much easier to work with, both for building and wicking. The clamps are not spring-loaded, but they are mounted at an angle and will easily move to the sides when unscrewing the deck screws. The ceramic piece that helps your wick from getting mushed now comes with a stiffer spring, and also features some vertical ridges that should be able to channel e-liquid easier to the sides.
The mesh strips available for the Profile 1.5 measure at 17 mm by 8.5 mm. They are a fair bit larger than the ones of the original—you could try using the older strips, but you’ll need to use much less cotton as you will end up with coils that have a smaller ID. There’s absolutely no way you’re going to fit these huge cotton pieces in the old strips, and there’s a chance that the flavor is going to suffer too. I didn’t bother trying it, but you can give it a try if that’s the only thing you have to work with.
Note that you can use the Profile 1.5 as a standard, non-mesh coil RDA. I personally don’t see much of a reason to do so, and there are far better RDAs out there for that, so I will only be discussing mesh builds in the following section.
If you have used the original, building on the 1.5 edition is going to be a breeze. But if you haven’t built a mesh RDA before, here’s a more-detailed-than-usual guide to building and wicking the Profile 1.5.
Take a mesh strip and roll it on the thicker side of the included coiling rod, to give it a rounded, semi-circle shape. Then unscrew the two deck screws, place the mesh strip on the one clamp and secure it in place. Repeat on the other side, and check that your coil has a nice round shape to it. If not, you can use the thinner side of the rod to shape it up.
Once you are done, I suggest firing the coil at around 20 watts, to check for hotspots and even heating. Mesh generally should work out of the box, but it doesn’t hurt to make sure—and you’ll also clean it up a bit. If you notice any hotspots, gently strum the strip with a pair of ceramic tweezers.
Then take one of the included cotton pieces and pass it through the mesh strip, slightly pushing the ceramic part downwards. This is where the design updates start to show their effects: the cotton strip fits much easier inside the mesh, and you don’t need to comb it meticulously and spend much time giving it a haircut. Cut the ends at an angle leaving the bottom part a bit longer, hanging approximately 2-3 mm outside of the deck. Slightly comb it if you feel like it, and gently tuck your cotton inside the juice well starting from the bottom. Easy-peasy.
It is very important that you saturate the wick properly before firing the mesh strip; you don’t want a burnt hit out of this RDA, I can promise you that. The best way is to drip, wait, repeat—you may also want to put the chamber cap on to avoid getting juice on your mod. Then drip or squonk and fire at a low wattage, and repeat at least a couple of times. Once your cotton is fully wet, you can go on and raise the wattage.
The airflow of the Profile 1.5 has also received some updates, but there’s nothing super-groundbreaking here. The three rows containing 19 tiny honeycomb holes of the original have been replaced by two rows containing 10 holes that are appx. 50% bigger. The top row is channeled through a very slightly angled slot that’s supposed to guide the air on the top of your build—more on that later on. Interestingly, while the sum of the diameter of the holes seems to be a bit smaller, the 1.5 feels like an airier RDA when compared to the original.
Turning the top part of the RDA allows for airflow adjustment; you can restrict the airflow starting from the top, and after it is fully closed you can start closing the bottom row. As a third option, both rows can be closed vertically, although you won’t be able to adjust the top cap and the air will only be hitting part of your build. There’s no way to close the bottom and keep the top row, but as you will read in the following section, that wouldn’t be of much use anyway.
To test performance, I tried all three included mesh strips.
The CHILL is designed similar to the Wotofo mesh for the original Profile, the TURBO is modelled after the older nexMESH strips, and the EXTREME is a standard, old-school type mesh strip without the flat parts at the ends.
According to Wotofo, the three strips are supposed to perform differently, and that’s true to an extent. The differences are not striking, but they are there. Used at 80 watts, the CHILL strip is a somewhat cooler vape, the TURBO is warmer and more flavorful, and the EXTREME is the warmest, with comparable flavor to the TURBO.
Bear in mind that all three strips performed fine at 90 watts and you can easily get 6-7 pulls before having to drip or squonk. Just make sure you give it some time in between, as chain-vaping at these wattages will make it pretty warm. That’s a major upgrade over the original, which often seemed to struggle at the higher end of the recommended wattages.
With the strips performing comparably, what ends up having a bigger effect in flavor is the airflow. I don’t like off-setting my airflow, so I mostly tested the RDA in two airflow configurations: fully open and bottom row open. With the bottom row open, I get a smooth restricted DL vape with banging flavor—my cream-based juices taste absolutely great on this RDA. Opening up the top row mutes the flavor significantly and makes me feel that the angle of the airflow slot is not steep enough to guide the air to the coils. It’s not that the flavor is bad when fully open, but there’s really no comparison between the two airflow options.
As I mentioned in the intro, the Profile 1.5 is an RDA made for squonking—or an RSA if you will. You can use it as a dripper, but you will have to drip very often and take care not to flood the deck. Its squonking system is designed very carefully, and I advise using it as a dripper only as a last resort.
Unlike most people, I am a fan of 1.5 editions of popular products. In fact, I feel that many V2s are actually V1.5s at best, and seeing 1.5 makes me feel that the designers are sincere. And that’s exactly the case with the Profile.
This edition of the Profile is better than the original in many ways. It beats the original in build quality, versatility, and flavor performance—although for the last part you’ll need to restrict the airflow a fair bit. And by enlarging the base and build deck, Wotofo made the Profile 1.5 a much easier RDA to work with too.
If you already own the original Profile RDA, you could skip this one—although I am pretty sure that sworn fans of the original have already placed their orders. But if you don’t own a Profile, and especially if you enjoy using squonk mods, it’s a no brainer. The Profile 1.5 is the definitive edition of the best mesh RDA on the market right now.
