The Wotofo Profile RDTA is the latest installation in the Profile series, following on from the Profile RDA, Profile 1.5 RDA and the Profile Unity RTA. An additional partnership in between Wotofo and Mrjustright1, the Profile RDTA enables you to build with single mesh, single coils or dual coils and can also be utilized as an RDA for squonking or leaking.
Disclaimer: I was sent out the Profile RDTA for review by Wotofo.

Style & Build Quality.
The Profile RDTA has an 810 coloured resin drip pointer on top. It has a metal ring around the bottom of the drip idea which matches the colour of the remainder of the RDTA. The drip pointer is comfy and great to utilize.
The top cap doubles as your airflow control. Turning the leading cap allows you to close off the airflow to your wanted choice. The leading cap is press fit and kept in by an o-ring.
When you initially take the Profile RDTA out of the product packaging the o-rings are really tight, but once it is being utilized they ease up with lubrication from liquid. A pain at first, they have a best restrictiveness in use. I ‘d rather them be too tight when dry and perfect in use, instead of just right when dry and falling off when lubed.
The airflow cap features the Profile logo on one side and the honeycomb air flow holes on either side. The airflow cap is press fit, secured with two o-rings on the develop deck base.
The airflow cap has 2 little tabs on the inside which lock the airflow cap in place as soon as it is fitted to the develop deck. This guarantees it does not turn when adjusting your airflow and also guarantees the air flow holes stay directed at your coils. They likewise cover the fill hole and air hole on the develop deck.

The build deck has two clamps to permit mesh strips to be installed. This ceramic plate will press up against your cotton to ensure it is held versus the mesh coil.
In the center of the ceramic plate you can see the top of the 510 connection pin, which is squonk ready. If you utilize the Profile RDTA in RDA mode you can put it on top of a squonk mod without having to change out the 510 connection pin.
The two slots in the ceramic plate reveal the devoted postless deck. You can install either a single or dual coil wire construct utilizing the postless deck. The coil legs are secured into the postless deck with 2 additional Phillips screws on each side of the mesh clamps.
The addition of the postless deck together with the mesh secures provides the Profile RDTA fantastic flexibility and Wotofo and Mrjustright1 have actually managed this while keeping the build deck good and neat.
There are two holes in each of the juice wells on the construct deck. These are where the stainless-steel rods sit, suspending into the juice tank.
At the side of each of the mesh secures is a hole. The larger hole is your juice fill port and the smaller one is a pressure relief vent to enable air to leave while filling the tank with liquid.
The tank frame has a removable glass tube on my evaluation unit, which Wotofo has encouraged will be PCTG in the retail variation. The tank frame has cutouts all the way around which permit you to see your liquid level and likewise double up as a knurling for unscrewing the tank. They likewise protect the glass tube to some extent.
The stainless steel rods hang into the tank and wick liquid from the tank to the construct deck via capillary action, feeding liquid to your cotton wicks.
I love the total design of the Profile RDTA. From the outdoors you are essentially looking at a Profile RDA sitting on top of the tank area. The inside exposes a build deck that enables you to use mesh, single and dual coils.
Transforming the Profile RDTA to an RDA is as easy as screwing and unscrewing the tank on the consisted of base plate, which then covers up the 4 wicking holes for the steel rods. Your Profile RDTA is then squonk all set, or you can swap out the squonk pin and use it as a dripper.
On my images of the build deck, you might see machining marks which Wotofo has recommended will not be present on retail versions of the Profile RDTA.
The construct quality on the Profile RDTA is area on. The machining of the threads is smooth and good. As discussed above, the tight when dry o-rings are the ideal resistance once the Profile RDTA remains in use and the o-rings have been oiled.
The airflow on the Profile RDTA is controlled by twisting the top cap. The leading cap features a stepped design which permits you to close off first of all the top row of air shaft, then the 2nd and 3rd rows simultaneously.
The airflow cap is locked in location, so will constantly be directed at your coils. I personally prefer a slightly limited draw and discovered closing off the top row of air holes offered me a perfect airflow.
Totally open the airflow provides a basically resistance totally free draw. If you like a really limiting DTL draw you can shut down the airflow entirely, or you can get used to throughout between.
Airflow on the Profile RDTA is smooth, not unstable at all and no whistles exist. The change of the top is actually smooth and enables you to shut down the airflow one hole at a time to truly dial in on your preferred draw.
Structure on the Profile RDTA.

As mentioned above you have the option of building with either mesh, double or single coils.
I needed to try the Clapton mesh strip first, to see how it performed.
Wotofo did advise me that the Clapton mesh strips offered have been dry scorched currently to check for hotspots and quality.
To set up mesh strips onto the construct deck you first untighten the Phillips screw on each clamp. The clamp is not spring loaded; you may need to knock it open when you have actually untightened the screw. You can do this with the tip of your screwdriver.
Next you take your mesh strip and location it on your included coil bending tool. Gently flex the mesh strip around the tool and it will handle a half moon shape. You then put the ends of the mesh strip into the clamps and screw them down.
You will then dry fire your mesh strip, which only requires to be done around 10W.
If you choose, to install your cotton you can utilize the included shoelace cotton or your own cotton. The thicker cotton included is for mesh constructs, the thinner cotton is for wire develops.
Feed your cotton under the mesh strip pushing down carefully on the ceramic plate to feed it through. The Clapton mesh is really fragile, so take care not to snag the wires when doing this.
The cotton is then cut to length on either side. I am not a knowledgeable mesh home builder and there are lots of methods for cutting cotton for mesh builds, so I’m not going to inform anyone how to do this as there are others who will be able to recommend far better than me.
If you are going to be using the Profile as an RDTA I would advise putting the construct deck onto the tank at this point and putting your stainless steel rods in place as it’s easier to do from the top than the bottom of the deck and you need to do it before you position your cotton in the juice wells.
Once the cotton has actually been cut to length the ends are tucked into the juice wells, so they rest on the wicking ports of the stainless steel rods.
Your cotton then requires to be filled and the tank filled with liquid.
The leading cap can then be replaced and you are ready to go.
I will not talk through installing a dual or single coil build as a Youtube video can demonstrate this better than I can with words alone.
I initially wish to discuss the flavor on the Profile RDTA. Using the Clapton mesh I settled on 65W and the taste is extraordinary. This is the very best taste I have experienced while vaping anything. Now, I need to say that I battle with RDA builds in basic since they are too hot for me at the wattage where the flavor truly comes through.
I’m not stating this is the finest flavor ever and everybody needs to run out and experience this. What I presume is that I am lastly able to experience the kind of taste that others do from rebuildables, because at 65W this is a best temperature level for me.
On the other hand I expect others that enjoy vaping at higher wattages may find the temperature to be too cool to them.
I used the nexMESH Turbo next and flavor is great, however compared to the Clapton mesh, no competitors.
I did put a double coil integrate in using the provided Framed Staple Claptons and ran into the issue that I constantly have with RDAs in general. It’s just too hot for me at the point where the flavor begins to pop. This is my issue and nothing to do with the Profile RDTA or any other rebuildable.
Now, the stainless steel wicking rods. I have actually tried every technique that I could discover for wicking and I couldn’t get the rods to keep up.
I want to accept this is down to my wicking, as others appear to have no concerns with it.
Disheartened, I took the tank off and utilized it in squonk mode for a while where it performed completely. I then tried once again with a different wicking method, however I faced the exact same issues. In the end I simply began turning it upside down to wet the wicks, which really worked fine. The cotton absorbs the liquid and I didn’t wind up with liquid running out of the air shaft or drip idea.
When I accidentally left my mod on its side when a parcel showed up at my door, I did experience leaking. It’s what I would have expected; the mess was horrendous, so I won’t be doing that once again on purpose.
The only other issue I encountered was the size of the fill port. It’s fine for needle tipped nozzles, however regrettably I have a huge nozzle on a 250ml bottle of liquid. I needed to transfer liquid into the tank using a syringe that I use for blending. Once again, this is my concern for not using basic bottles, but believed i ‘d mention it for anybody else that uses larger bottles and nozzles.
Overall, I’ve loved utilizing the Profile RDTA. I’m going to have to get some Clapton mesh strips for use in other mesh rebuildables in the future due to the fact that it blows basic mesh out of the water.
It hasn’t lacked its frustrations due to the wicking from the stainless steel rods, which I am willing to accept may be down to my wicking. I can’t state they don’t work, however I haven’t handled to make them work for me.

The build quality on the Profile RDTA is spot on. As discussed above, the tight when dry o-rings are the ideal resistance once the Profile RDTA is in usage and the o-rings have actually been oiled.
