First off, let us check out what the Wotofo Profile Mesh RTA has to offer in terms of specifications:
- 25mm diameter
- 48.5mm height
- 3.5ml standard capacity (5ml with expanded capacity)
- nexMesh strip (coil): 0.13ohm best at 60-70W
Here’s what you get with the Wotofo Profile Mesh RTA:
- 1 x Wotofo Profile RTA
- 1 x spare 5ml Spare Glass
- 1 x mesh strip bending and adjustment tool
- 1 x set of nexMesh coil strips
- 1 x set of 6mm diameter Wotofo Agleted Cotton
- Spare parts (including springs, o-rings and chimney extension for higher capacity tank)
In collaboration with MrJustRight1 and TheVaporChronicles, Wotofo brings the quintessence of one of the best mesh RDAs to tank fans in the form of the Profile Unity RTA. Sporting a classic outward appearance, the Profile Unity mesh RTA resembles a traditional vape tank but loaded with numerous enhancements such as.
- A single row of five 1mm side airflow holes on both sides like an MTL tank upgraded juice flow that can soak a super thick cotton wick
- Deep wicking channels around the easy to use mesh strip build deck
The top-fill cap groove and channel type of locking mechanism for a quicker release and faster fill up. The edge of the fill slots features an angled tip that allows the tip of the dripper to rest against the cutouts. The lip plays the vital role of keeping the tip of the glass drippers from snapping or cracking. The narrow width of the fill slots; however, causes a slight back up with a high VG vape juice.
A considerably thick, blue-tinted resin 810 drip tip that is placed comfortably against the lips comes pre-installed. This is due to the round beveling on its outside edge.
The drip tip occasionally comes unseated, probably due to uneven pressure. Although the drip tip is somewhat loose in the cutout, rest assured it will neither get stuck nor drop. There’s a lock and turn type system for the deck. It has matching notches on inside of the deck and tank. This design ensures the air and juice flow stay lined up properly.
You can find a white, spring-loaded piece at the center-right in between the clamps. The central piece facilitates the smooth operation of the whole system simply by pressing the cotton upward evenly against the mesh strips, carefully avoiding the hot spots.
The gallery above has a side by side with two types of mesh strips that fit the Profile series build decks. The slightly more standard net style mesh strip, measuring at 0.18 ohms is placed on the left, while the right is the nexMesh triple thickness mesh strips, a couple of which are included with RTA are located on the right.
The amount and size of holes on the nexMesh vs the standard is noteworthy. Both strips perform significantly well with the left requiring less power, while the right seeming to generate a thicker vapor.
How To Build The Wotofo Profile Unity RTA
Wotofo provides a pair of nexMesh OFRF mesh strips and some agleted (think shoelace ends) organic cotton 60mm x 6mm, a sizeable piece of cotton.
The thickness is ideal to fit right under the mesh and pave the way for appropriate pressure to be applied by the deck. Wotofo has come up with two varieties of pieces of cotton including organic cotton fiber blend based strips and traditional organic cotton.
If you are looking for the best results, use the agleted Wotofo XFiber organic cotton 10-pack and the Wotofo nexMesh strips.
How to build the Profile:
- Loosen the screws just enough to allow for a slight gap to open on both of the clamps.
- Use the thick end of the stripping tool to form the mesh strip.
- Insert both ends of the now bent mesh strip into their respective slots at the same time, ensuring both ends are fully inserted. Secure both clamps.
- Pulse the deck (dry burn) at a low wattage just long enough to ensure even glow. This only takes a split second, so don’t overdo it. If it isn’t glowing evenly, the strip may need to be re-seated in the clamps. If the strip gets bent once in place, use the tool to reshape the coil.
- Pull the agleted cotton underneath the now curved mesh, applying downward pressure on the deck (avoiding the mesh if possible) until strip is centered centered
- Cut the cotton as shown in the photo above. The angle cut is important to prevent tugging the top of the wick away from the edges of the mesh strip once the cotton is tucked into the wicking channel.
- Apply the juice to soak the wick and then shape the sides of the cotton with the edge of a pair of tweezers before inserting the deck into the RTA.
Replacing standard round and particularly Clapton wire with mesh strips seems to be a reduction in the amount of time needed to heat the wire and start producing vapor.
Using the 3.5ml glass instead of the 5ml glass includes a tiny chimney extension like found on other tanks that do not utilize bubble glass to generate extra volume.
There’s negligible difference in terms of performance on both the standard and 5ml setups, however, the mesh is considerably thirsty, making the 5ml setup a reasonable settlement for a negligible loss of flavor.
The cotton wicks surprisingly fast as a result of good juice flow and the wicking channel design.
A series of five 1mm holes on each side provide airflow with an easily adjustable ring. The airflow holes are lined up with the top of the coil strip.
When you keep the airflow holes open, you’d get a pretty good flavor, although it a bit airy, it is not washed out as with a lot of other tanks at max air setting. The Profile RTA delivers the best performance with its air restricted.
If you want a more restricted hit with a warmer cloud, try 2 holes at 60W.
If cut down to just one hole, the draw gets a bit too tight but the vape remains very warm, offering sharp flavor and a dense cloud.
Each airflow setting offers a smooth draw and increasing nouse with each reduction as expected, but developed just a bit of whistle when restricted heavily.
In other words, the Wotofo Profile Unity RTA can be described as a mesh done right for the rebuildable vape tank. Using cotton and the Wotofo mesh strips, the deck hardly takes a couple of minutes to build and you can enjoy a very flavorful vape, coupled with enjoyable restricted lung hit, and dense vapor production. On the downside, the drip tips do not stay seated completely.
- Amazing flavor!
- Smooth side airflow (best performance at 3 – 2 for restricted direct lung)
- Very fast wicking when built properly (angle cut the wicks!)
- Super easy to build thanks to strips and agleted (think shoelace) cotton
- Dense, cool clouds at 60W, warm and brighter flavor @ 65-70W
