I was sent the profile RDA by Wotofo for the purpose of this writing. I am merely giving an account of my experience and opinion of this product. The Profile was developed in collaboration with wotofo and MrJustRight1.
I have never used mesh as a heating element for vaping. I have used it previously for wicking, however, that certainly does not apply here. Upon opening the package, you are met with the profile rda, a nice low profile 810 drip tip and squonk 510 pin installed. Additionally, you will have a spare 810 tip, single clapton coil, thick lace cotton, 2 mesh coils, o-rings, screws, non-squonk 510 pin, allen key, spare springs, spare clamp screws, screwdriver, and mesh wrapping tool. The profile rda has the profile logo engraved on the barrel; and, includes the “profile” logo on the barrel, with “wotofo” and “mrjustright1” engraved on the deck. Each piece of mesh is 16mm X 6.8mm and 0.18 ohm, the included framed staple coil is a 0.33 ohm resistance.
Immediately I was impressed with the construction quality of the RDA. The overall diameter is 24mm; however, the double o-ring deck is 20mm. The thick-walled barrel is most impressive, as it tends to give it a nice weighty feel of quality and reduces chamber size. The rda also has an interlocking feature allowing the barrel to lock in place with the deck for consistent, direct airflow and ease of screwing the atomizer in place without spinning.
The two things that struck out to me the most with this rda, aside from the construction and perfect O-ring tension, were the way the wicking is done and the ease of installing the mesh coil.
The first thing you do, is take the build tool and hold the skinny end while wrapping the mesh around the wide end. This bends it into a perfect half circle with a base of approximately 6mm in width. After that, you just unscrew the clamps on the deck, slide the mesh in and tighten it down. You will see a white ceramic plate in between the deck clamps with a hole in the middle. The hole is the squonk hole, allowing juice to directly saturate your wick and coil, limiting the amount of capillary action needed to saturate the coil.
The plate shown, is spring loaded, the spring applies pressure from the bottom, to force the cotton against the coil. This works to limit hot spots, or in the case of mesh, spots without juice contact. I submitted myself to a dry hit with this, for scientific purposes, and I must say… constant contact to the cotton and wick, will be highly advisable to avoid an unpleasant experience. I give wotofo and MrJustright1 credit for developing this idea. One thing I did notice was that the spring tension appeared to be a tad on the loose side, perhaps it was to allow for the cotton to thread through the space easy. They do offer spare springs, which are easy to change if necessary, by unscrewing the squonk hole from inside the ceramic block.
Also, I found the easiest way to cut the wick was to cut it on an angle in a similar to method to that used for some of the early rta’s with small wick ports. – thinking broad shoulders with tiny legs.
Cutting the excess in this way seamed to alleviate the taste of having too much cotton as well as allowed the wick to saturate more efficiently to alleviate the loss of juice. I will say, that it does require a lot of cotton as the mesh is thin but as you can see the nature of mesh provides large space to fill. Still, the mesh heats immediately. There is zero ramp up time on this at all. However, it lends itself to be more of a flavor rda than clouds. Even with the 19, 1mm airholes in a honeycomb pattern on the barrel. I found the flavor to be best with the top of the three rows of holes closed off. Additionally, it is worth mentioning that the air holes are small, and the inside of the stepped airflow control is the same color as the outside, making it a tad difficult to see how many holes are open or closed. This was not an issue as I simply adjusted for taste and left it alone. The airflow design also makes the airflow smooth and quiet. I did not get any turbulence at all from this. Additionally, I was able to fill the rda with juice while squonking, watching the juice fill over the coil and not lose a drop of juice out of the side airflow.
Should you decide to use this as a traditional rda, you can simply change the 510 pin. The closed 510, has ample protrusion for hybrid safety and the placement of the coil lends itself to be leak resistant for ample juice dripping directly onto the coil or mesh. As you can see the airflow is set high but the bottom two rows of holes line up perfectly with the mesh. The kanthal mesh supplied suggested a power setting of 45-65w. I found to prefer it around 60w.
Single coils?
Yes, this can be used as a single coil rda without the mesh. I used a 4x28/38g ss316 clapton, placed high above the deck to ensure direct airflow. I found the single coil usage to be a little more airy or anemic than I would prefer. The real estate used by the mesh really is hard to duplicate with a coil. Both coil and mesh did provide an amply satisfying vape, I merely preferred the mesh, for both flavor and vapor production. It should also be said that the ability to get the quality of vape I received with 60w is great for battery consumption when compared to a similar vape with a dual coil build, requiring 75w-85w. Combining the power usage of a single mesh coil, with the flavor I experienced, causes me to put this in the win column.
Now the question… what did you think overall?
In all honesty, I found myself really enjoying the quality of vape I experience with this for the power applied. After a few weeks of use, I noticed that I was getting the best flavor from it using sweet fruit juices like an apple tart, over cereals or savory desert flavors. I found the build quality, ease of coil and wick installation, o-ring tension, ease of airflow adjustment and ability to use all of my 810 driptips to be huge pros. I also find this to be a very attractive piece of low-profile gear, as it is 32.5mm tall, shorter than a goon, yet taller than a hadaly.
The only real con, I found was not so much its flavor from a single coil; but, more of a comparative issue. If I wanted a single coil atomizer, I would probably consider something that excels at single coil, as a dedicated RDA- ie the recurve. If I wanted something that really excels at mesh, but gave me the option to get a good vape from a single coil, I would definitely pick this up.
Having not used mesh in before, I can see the attractiveness to using it, I can see it becoming a go to material. This is not just for we the hobbyist; but also, for folks with dexterity issues or those wanting to build, but not having the time to do so. I can also see this being ideal for the vapor that has been using a subohm tank for a while, and wants that first rda experience, but scared to build. They can buy a pack of precut mesh and wick for this rda and have a great rda or rsa experience that will easily rival any number of rdas on the market. Not only is this rda amazingly easy to build and wick, but the flavor, at least in the case of the profile, is excellent.
