There’s no doubt about it, Wotofo make great mesh tanks. The Wotofo Profile has long been one of the best mesh RDAs out and it’s now being followed up by the Profile Unity RTA. This tank is not only a collaboration between Wotofo and MrJustRight1, but also with the Vapor Chronicles — a unity of three of the largest names in vaping.
The Profile Unity keeps the same great build deck as the Profile RDA. It comes with both 3.5ml and 5ml glass tank sections, a smooth adjustable airflow for DTL hits and features a conical chamber for enhanced flavor.

The Profile Unity is a 25mm RTA. With the 5ml glass tank section attached it’s quite a tall tank. Similar to the Profile RDA, the Profile Unity has a very minimalist design. It’s a straight tank with no curves and the glass tank section is also straight rather than bubbled.
The top cap has some ridges along the edge, as does the base of the tank. However, other than these small design features and a reserved Profile logo on the body of the tank, there’s no other styling. It’s a straightforward and simple looking RTA.
The machining on all of the pieces is very good. From the top cap to the base of the tank everything is well machined and fits together perfectly. Wotofo’s tanks have always been well made though so I can’t say that I expected any different from this RTA.
The drip tip on this tank is great. It’s a thick wide bore 810 and it’s made of resin. This drip tip is rounded and is a change from the thin drip tips that usually come with tanks. You can tell that it was created as part of the design process rather than as an afterthought. I really like it.
The Profile Unity uses a threaded, tongue and groove top cap. It goes on and comes off with just a quarter turn and catches really well. It’s a pleasure to use and very secure. The fill ports, on the other hand, could use some improvement.
The fill ports are nice and wide but they aren’t very large. You have to be careful when filling the tank otherwise you’ll end up with a mess. Additionally, while they are slanted downwards to funnel into the tank, they’re so thin that thicker ejuices can collect on the rim.
There are two glass tank sections included with this tank: a 3.5ml and a 5ml section. Using the 5ml glass requires the use of an adapter (included). To change the glass you’ll have to unscrew the top portion of the tank, the piece underneath the fill cap. Next, you’ll want to screw in the small adapter onto the chimney of the tank. Once this is done you can install the 5ml glass section and reassemble the tank.
On each side of the tank there are five airflow holes that increase in size. These holes are slanted downward and feed into the build deck through holes on the inside of the domed chamber. Although the airflow does make a little bit of noise when restricted there’s no turbulence or whistling.
Fully open you get a smooth direct lung draw with a bit of restriction. With the airflow restricted at three holes open you get a more restricted direct lung draw. Down to one hole open you get a very restricted lung hit, however it’s not tight enough to be considered MTL.
Restricting it down to one hole makes the vapor much too hot when vaping at the coils recommended range of 60-75W. I decreased the wattage to 40W to make it more comfortable but the flavor and vapor production definitely take a hit.
Instead, I preferred vaping the Profile Unity with two holes closed. This is where the tank performs at its best and I would suggest you try the same. You get a smooth, tight draw while still allowing enough air for the mesh coil to deliver optimal vapor and flavor.
The build deck on this RTA is almost exactly the same as the the Profile RDA. There are two clamps that are specifically made for use with mesh coils. The main difference from the Profile RDA is that there are two wicking ports built into the side of this deck.
This RTA is unique because there are both top wicking and bottom wicking channels. This means that juice will feed in from both the top and the bottom of the coil for more effective wicking. There’s a certain trick to building and wicking this RTA to make best use of these channels but I’ll get into that in the building section.
While this deck can be used with regular round coils, I would consider the Profile Unity a strictly mesh RTA. The small conical chamber is made specifically to accommodate to the low-profile mesh coils so other coils will have a hard time fitting. If you’re looking to use regular round coils there are numerous other options available on the market that are better suited to their use.
The screws on this deck are pretty good. They can be adjusted with either Flathead or Phillips head screwdrivers and the screws work quite well. You simply insert your strip of mesh into the clamps and tighten them down securely.
There’s a spring-loaded, center block in between the two clamps on this deck and I’ve found it to be quite useful. The cotton needs to be in full contact with mesh coils for it to work properly, otherwise you’ll end up with hot spots and a burnt coil. This spring-loaded block pushes up on the cotton and ensures that it makes full contact and is tight to the mesh.
Building on the Profile Unity
There’s a certain method needed to build a mesh coil properly. If you haven’t don’t be intimidated. It’s easy once you know how to do it! Thoughtfully, Wotofo include everything you need to build the coil: mesh coils, agleted cotton, a mesh shaping tool and a screwdriver.
The included mesh coils are 0.13ohm nexMesh coils. These are made by OFRF and are known as some of the best mesh strips on the market. They’re best used from 60-75W and are the perfect size to fit into the clamps on the build deck.
I started by loosening the clamps on the build deck. The mesh is super thin so you don’t need to loosen them too much. Next, I took my nexMesh coil and the included mesh shaping rod. You’ll want to roll the mesh onto the rod in order to shape the mesh into a smooth semi-circular shape.
Insert the mesh into the clamps and tighten them down. You’ll want to pulse the coil at very low wattage (10-15W) once or twice just to ensure that it’s glowing evenly. Once this is done it’s time for the cotton.
The included cotton is fluffy and thick — perfect for use with mesh coils. To make it easier to insert I pushed down slightly on the center block while threading through my cotton. Once it’s all the way through the block will push back up on the cotton to ensure that it makes full and even contact.
When cutting your wicks you’ll want to cut them at a 45 degree angle. Cut them so that the bottom is wider than the top. It should look sort of like a bow tie when it’s all done. This is so that the top portion can still be wicked by the upper juice ports. Tuck in the cotton at the bottom but ensure that it isn’t too snug. You’ll want to cover the wicking ports but it shouldn’t be stuffed in too much. Fluff the upper portion of the cotton to catch the upper juice ports and you’re all set.
In the couple weeks that I’ve been using this tank I’ve fallen in love! The performance is spectacular and it’s definitely one of the top RTA’s out right now, period. When wicked correctly there are no dry hits at the recommended range of 60-75W even when taking multiple hits in a row. The flavor is also phenomenal. Anyone who is saying otherwise surely didn’t wick this tank correctly.
Vaping this tank at 68W with three holes open was the sweet spot for me. The vapor was warm and the flavor was excellent. I tasted all the right notes in my ejuice. The only potentially negative thing I have to say is that this tank guzzles ejuice. Even with the 5ml glass tank section I was going through two refills a day at the least. The flavor is so good though, I think I can live with using more ejuice.
As I mentioned in the airflow section this tank delivers anything from a direct lung draw with a bit of restriction to a tighter restricted lung hit. It’s not a tank made for MTL but there are great RTA’s like the BSKR V1.5 Mini if that’s the type of hit that you’re looking for.
Wotofo have created another amazing tank. It’s got the same amazing flavor as the Profile RDA but in the convenient form of an RTA. It’s not the most modern or high-end looking tank on the market but its performance makes up for it. As long as you wick it correctly, you’ll be getting the best flavor possible out of a rebuildable tank.
If you haven’t built on a mesh deck before, it’s worth learning for the phenomenal flavor. Just make sure to shape the mesh into a perfectly smooth semi-circle and fluff up the top of your wicks. Anyone who likes mesh RTAs and a restricted lung hit will love using this tank.
