Today I’m going to be taking a look at another new product designed by YouTuber Mr Justright1, the Wotofo Profile PS Dual Mesh RDA.
You’ve got to hand it to Wotofo they have designed a special 28.5mm RDA that takes dual mesh strips; it is a versatile parallel or series dripper RDA as well as squonk RDA.
Wotofo as a company is based in China, they have been operating since 2009 and have bought us devices like the Mdura Pro, Dyadic Sqounk mod and Profile Squonk mod and RDA toppers like the Serpent BF RDA, Srpnt RDA, Profile RDA, Freakshow v2 RDA and the Nudge RDA, and many more!
Wotofo has released the Profile PS Dual Mesh RDA in 6 colours.
What Can We Expect From the Wotofo Profile PS RDA?
I can count on one hand how many dual mesh RDA’s are out there (not many), and to be honest I am quite fascinated by this one.
In the past I have always used mods that could handle parallel or series built coils like the Wismec Noisy Cricket V2.
Never in my wild imaginings would I think of changing from parallel to series just by swapping out a connection pin on the RDA!
But this is exactly what Wotofo and Mr Justright1 have done with this topper, I really believe this RDA to be a worlds first in RDA innovation.
Included with the kit are 4 pins to allow you to drip or squonk in series or parallel mode!
This product was sent to me for the purpose of review.
As always my thoughts and views are my own after considerable testing.

Design and Build Quality
The Wotofo Profile Dual Mesh PS RDA is made from stainless steel, it has an excellent quality of manufacture and design, and in the time I have been using this topper, it’s been solid and sound.
Wotofo has presented the Profile PS nicely in a card box with a plastic sleeve, with the extras under the foam tray.
Wotofo Profile PS RDA – Overview
As you can see I was sent the gun metal version.
It measures in at 35.5mm tall, and has a wide tank diameter of 28.5mm.
The RDA is a hefty little beast weighing in at 6.7oz, and comes with a low profile 810 resin mouthpiece preinstalled.
The extras bags have all the normal things you would expect to find including 3 of the 4 connection pins, I will say they have been a bit stingy in only supplying 2 mesh strips!
But no worries before this review in my tests with the PS I used kanthal mesh cut to size.
This RDA will dismantle into 6 parts – 9 parts if you take into account the 2 series and 2 parallel pins and parallel adaptor screw.
Wotofo Profile PS RDA Airflow Ring
Has a knurled decoration for easy movement within the barrel.
A low profile replaceable 810 mottled resin mouth pieces sits flat on a slightly raised platform and is held in position by an embedded O-ring.
The airflow ring consists of 27 honeycomb holes on each side of the ring in 3 rows; along with a single O ring help’s turn the cap in the barrel.
Inside the airflow cap you will see that it has been domed for improved flavour, any condensation or liquid will also drop back down to the cotton.
Wotofo Profile PS RDA Barrel
The stainless steel used for the barrel is quite thick and weighty, the barrel airflow is handled by 3 wide slots on each side.
And has “Profile PS” engraved on the front for advertising. BTW the PS stands for Parallel Series.
Looking inside the barrel you will see that it has 2 projections these will lock into place with the build deck, so the barrel remains stationary while turning the airflow.
Wotofo Profile PS RDA Build Deck
The bottom of the PS has all the usual information.
The PS comes with the parallel gold plated 510 connection pin preinstalled which can be swapped out for any of the other 3 pins, under the parallel pin is an adaptor for use with only the parallel pins.
The 810 connection threading has been turned well.
The sides of the base and post have been sand blasted to give a different look to the deck, and the two side wire clamp screws have been recessed in cut outs that hold the barrel in place, the base has an O ring for the barrel to slip over.
Looking at the build deck you will see one central post, it has wire clamps at each end and 1 on top, this clamp also serves as the squonk valve with a hollow screw.
Each of the side clamps has a white peek insulator plate on springs that serve to keep your cotton tight to the mesh strip.
The liquid well is deep and will hold up to 3ml of liquid and cotton!
A lot of thought has gone into this RDA, the design is sound and the quality of workmanship is excellent.
My biggest and only complaint after taking the Profile PS out of the box is it was swimming in machine oil, I mean the whole thing was coated, a quick wash sorted that!
So How Does the Wotofo Profile PS RDA Perform?
For liquid I will be using an old favourite of mine TJuice Red Astaire, I made 120ml from TJuice’s 30ml DIY liquid concentrate.
How to prepare the Profile PS RDA for use! A Basic guide
Choose which pin you want to use, parallel or series in either squonk or drip mode, I will be using the parallel closed pin to start with.
- Find your coil tool and bend the mesh strips.
- Seat the mesh into the clamps! Ensure the mesh is straight and level before tightening down the top clamp screw!
- I like to heat the mesh at this point by pulsing on a low wattage. You don’t have to do this, but as my fingers have been all over the mesh it’s advisable!
- Load your cotton – comb and trim and tuck into the deck.
- Dampen the cotton with liquid.
Reassemble the Profile PS RDA and enjoy!
A word about Series V Parallel mesh builds
Loading this RDA for either series or parallel is exactly the same the only difference will be the pin chosen.
The mesh supplied by Wotofo are 0.3Ω strips this means that for a series build with this RDA both coils will total 0.6Ω and for parallel with the same build will total 0.15Ω.
Using either of the series pins will help to preserve your battery power, especially for those who use single battery squonk/regulated mods.
In squonk mode as you push the bottle the liquid will waterfall from the valve over the coils and cotton.
Wotofo Profile PS RDA in use
I personally found the PS a bit fiddly to build on due to my arthritis, you have to hold both of the mesh strip ends into the top clamps then screw down the hollow squonk valve/screw.
In parallel drip mode for me 55 to 60w with the airflow cut down to half was just about right for my micro lungs lol.
In series squonk mode using my profile squonker I fired this beasty at 45w topping off at 55w with the same airflow.
Both modes gave fairly good flavour with excellent vapour production; I did notice that the series squonk runs a little warmer than the parallel dripper.
For use with hybrid mechs, the series and parallel 510 pins do sits out enough for me to be happy in recommending this RDA for use with these devices.
- Good quality
- Nicely designed
- Thick vapour production
- Good flavour
- Fiddly but easy to build on
- Choice of series or parallel pins
- Swishy airflow
- Shop around for cheapest retail price
I don’t have any serious concerns with the Wotofo Profile Dual Mesh RDA.
- The amount of machine oil in this RDA when new was horrible but fixable
- Only 2 pieces of mesh come with the kit
- Low profile drip tip
Final Review Verdict
I am very impressed by the vapour production that the Wotofo Profile PS RDA produces its thick and cloudy, the flavour production was fairly good.
Only supplying 2 mesh strips was disappointing! I’ve also ended up changing the 810 drip tip for a slightly longer one!
Innovation is something I always look for with vaping products and have to say I think Wotofo has nailed it with the changeable series and parallel pins.
Would I recommend the Profile PS Dual Mesh RDA?
I would have no qualms about recommending this RDA, for intermediate and experienced users.
Would I buy this RDA again due loss or damage?
“Yes” I can see myself buying another as replacement or even as a 2nd topper!
