Hi ECF members, In this review i take a look at the Profile rda by Wotofo. The Profile rda was sent for the purpose of this review by Antonio from Wotofo.

Wotofo Profile RDA - Excellent rebuildable vaping devices, RDAs, RTAs from Wotofo



Introduction

Wotofo have been releasing some top notch products of late and their latest RDA may raise a few eyebrows as it's a Mesh RDA which haven't exactly set the vaping world on fire as yet. The Profile RDA is a collaboration between Wotofo and Mr Justright1 and they believe they have come up with the solution to turn the fortunes of a mesh RDA around, so lets have a look.

In the Box



Contents:

1 x Wotofo x Mr.JustRight1 Profile 24mm RDA
1 x 6mm Agleted Cotton Wick
1 x Extra 810 Drip Tip

1 x Spare Parts Bag (4 o-rings, 2 post screws, 1 solid centre pin and 2 spare ceramic support block springs)
1 x screwdriver + Allen key
1 x 0.33 ohms 3 mm Framed Staple Clapton Coil
2 x Mesh Coil Sheets 0.18 ohms rated 40-60 Watts

Aesthetics

The Profile RDA comes in typical Wotofo Green packaging with viewing window, and as well as the RDA the box is packed with goodies. I received the Blue version, it's also available in Stainless Steel, Black, Gunmetal, Gold and Rainbow, mine came with a resin 810 drip tip installed, you also get a second 810 drip tip and it's a standard fitting so you can use your own if you wish. The RDA is 24mm in diameter and rather short, the sleeve has a Profile logo printed on the front in White and both sides have 3 rows of small airflow holes which also add to the aesthetics. The base has plenty of branding, safety stamps and the installed BF Gold plated 510 pin protrudes nicely (the kit also includes a standard pin). The sleeve is very thick and all the machining is excellent, it's very good quality.

The Airflow

The Profile RDA has side airflow which enters the chamber each side by 3 rows of small airflow holes on the outer sleeve, we have 6 holes in the top and bottom rows and 7 in the middle, that's a total of 19 each side. The inner sleeve is stepped so you can have either 2 rows open or 3 rows open, there is no option to have just one row open but because the airflow is a series of holes rather than slots this does restrict the amount of air so you would want at least 2 rows open anyway. The sleeve locks onto the base so the airflow is perfectly lined up with your mesh or coil (if you decided to do a single coil build).



Using Mesh in an RDA Issue

Mesh is becoming the way to go with stock coils upping the flavour and giving coils more longevity but mesh RDA's have not been met with the same enthusiasm being inconsistent with flavour and renowned for dry hits. Mesh gives great flavour, yes that's just my opinion but it is an opinion shared with countless others but the mesh needs total contact with the wicking material and a combination of the flexible mesh and cotton which expands, then shrinks as it dry's and also can sag and change shape as it's constantly expanding shrinking and sagging means with all the best will in the world trying to keep cotton touching the entire surface area of the mesh is a big problem. It has worked perfectly with stock coils as the cotton is packed between the mesh and the outer shell of the coil head so the cotton always covers the mesh surface area, if only there could be a solution so mesh can be enjoyed in an RDA, Read on!!!



Spring Loaded Ceramic Seating.

Mr JustRight1 has come up with the perfect solution, between the posts on the Profile RDA we have a Spring loaded Ceramic seat directly underneath where the Mesh domes over from post to post. The Ceramic seat pushes the cotton against the mesh and has the cotton expands, then shrinks etc the ceramic constantly pushes the cotton against the mesh with the spring allowing it to lower or raise to achieve this.



The Deck and Build

The Deck is very simple with a vertical sitting clamp each side for the end of your mesh to slide into. The grub screws are on the sides, so simply loosen the screws, slide your mesh ends evenly in place and tighten the screws it's that easy. The grub screws are combo flathead/phillips which is a plus and to make it even easier you are supplied with a simple tool to bend the mesh around before fitting, it bends the mesh to the perfect shape (the simple ideas are always the best). Before wicking pulse your coils at about 15w (20w max) to get rid of any hot spots and burn off any residue from manufacture. Wicking is done very generously and you get supplied with 2 mesh strips cut to size and 1 shoelace cotton which is 6mm in diameter purpose made for wicking the mesh, both the mesh strips and cotton for the Profile RDA are available in packs of 10. The deck also allows for a standard single coil build (a coil is included), you need both your legs facing the same way and again you just slot your legs into place then fasten the clamps, it means your coil is raised up but that brings it in line with the airflow, when i tried the single coil i wicked it quite generously and it worked very well.

My Experience Using The Profile RDA

The flavour from this RDA is matching the Warrior which i was equally impressed with. I used it with the BF pin and fair enough i didn't chain vape but there was no hint of a dry hit and the excellent flavour was consistent, Mr Justright1 seems to of come up with a game changer idea with the ceramic spring loaded seat which works perfectly. The flavour though is not just down to the fact we are using mesh as the single coil build i did also gave impressive flavour. The thickness of the sleeve wall is 2mm which means the deck is only 20mm so when you peer down inside the top-cap at the build it all looks very cramped for space but what this is actually doing is reducing the chamber. Also i always find multi-hole airflow rather than slots gives good flavour as well as making the airflow very smooth and again the Profile isn't just matching the Warrior for smoothness but possibly just beating it which i wouldn't of thought possible. The Profile works really well with the BF pin on a squonker and i suffered no leaking. The sleeve fits with double o-rings and locks sitting on a bottom shelve, the airflow holes are both tiny and quite high so not getting any leaking was no surprise. If i was going to be very petty just to find a con it's that the airflow holes are so small and outer and inner sleeve are the same colour so it's not easy to see how it's set, but if you set it to 2 rows or 3 rows (i just had all 3 rows open) before putting the sleeve on it's not an issue.



Closing thought

Wotofo and Mr Justright1 got this one justright!



Pros

High build quality (excellent machining)
Aesthetically pleasing
Flavour for days
So smooth airflow
Spring loaded ceramic seat
Mesh or single coil build
Build very easy (both mesh and coil)
Included Mesh and coil
Included purpose made cotton for mesh build
Loads of extras
Tool to shape mesh
Locking sleeve
Stepped inner sleeve
Worked really well with BF pin
Suffered no leaking


Cons

Not easy to see how airflow is set (very petty)



I would once again like to thank Antonio from Wotofo for supplying the Profile RDA for the purpose of this review.

Nice write up and pics.

I got one a couple of days ago. It won't replace any of my other mesh RDA's, but was well worth trying it out.

Which other mesh RDA's are you using? all the ones i have used in the past have given dry hits and inconsistent flavour, the occasional flame as been known!

I have 3 Vandy Vape Mesh RDA's, 5 Digiflavor Mesh Pro RDA's, now this Wotofo Profile (and an old school NoName NoGain). The Mesh Pro's are my favorites. They are fire breathing dragons, but I've never had a single dry hit (in any of my mesh RDA's) and they deliver monster flavor rich vapor with the low sub Ω builds I give them (0.12Ω-0.15Ω). I DLH, and can get several full pulls before I have to squonk/drip to whet the wicks again.

Dry hits and flames commonly come from dry wick that is not making solid contact with the mesh and that is not kept well joosed. Crud on the mesh can also cause hot spots, so it's prudent to dry burn your mesh occasionally (way more often if you vape sweet liquids that are known to gunk up coils).

I learned early on the the key to easy mesh RDA's is the wicking. You must always have constant firm contact between all the mesh and wicking that it draws from, and keep the wick soaked. IOW, no non contact areas between the mesh and cotton - they will give you a dry hit. In my favored DMP's I use a massive amount of pulled and rolled CBV2 as tight under the SS mesh as I can get it. I don't try to fish wick under the installed mesh... I actually release the mesh from one clamp, put what looks like way more wick than can possibly fit under it or even in the RDA and force that loose SS mesh tail down into the clamp to tightly compress the cotton. Then simply groom the tails to fit the available deck/drip well and tuck them in.

Quick picture of the build in one of my DMP's.

Yeah people know why they give dry hits etc is down to the wicking but us mere mortals just struggle to get consistent good results even knowing that. If you have the knack and have no problem with keeping the cotton in contact with the entire mesh while wicking well then happy days because mesh equals flavour in my experience, but most of us have struggled with mesh RDA's so the profile is a great option.

My "knack" for consistency simply comes from lots of practice... 5.5+ years of vaping and doing my own DIY 24/7, and not being willing to settle for anything less than my perfect vapes. I crossed the dry hits bridge many years ago, and never revisited it. I think where this RDA will shine is for folks who won't or don't want to go the extra mile to learn how build other mesh rda's right. This RDA would have very few or no cons at all for most folks who haven't experienced better. I'd probably keep using this one as well if I can work out my preferred Ω SS mesh and P&R wick builds in it. But the mesh is so small I doubt it.

Yeah we are talking about only about a 180 degree arc compared to almost the full 360 degree you get on the atty's you favour so because you have the wicking down to the tee they are going to be superior. I obviously in the review used the supplied mesh which is gives good flavour but i will be using SS in it and giving it a go with Replay.

I'm not a fan of KA1 mesh. So I cut down to size and put a SS316 Mesh build in the Profile that came in at 0.15Ω. It hits at about 115W on the P67 mech with a fresh battery. This SS build @ 28A doesn't leave much of an unused ceiling on the true 30A VCT5A batteries I use, so it would probably be more comfortable on one of my dual parallel mesh squonk mods that uses two 30A batts to share the load. Also tried it on a dual series TC mod (8.4VDC) with two 30A '650's and got about the same vape at 60W-70W. I have a lifetime supply of the SS mesh, so I'll keep this new mesh RDA on line.

The Profile should be an easier 'first mesh RDA' to get right first try for those who want to try out this kind of RDA. Just keep the smaller wick this RDA holds well saturated with joose and you won't get any dry hits with a reasonable vaping regime.

My system for vaping it: Even with my DLH's and the AFC's wide open for max air I take 15 pulls between squonking with no indication at all yet that it might start dry hitting. FWIW, once you get to know the mesh RDA's (that are built and maintained right) you'll recognize when a wick is starting to run low of joose on them. It is a sudden change because they use so much joose for every pull, but there are fore warning signs that tell you to whet the wick again (vapor/flavor drop offs are easily noticeable).

All IMO-YMMV

Hi im new to this forum got my wotofo mesh RDA a day ago and i intended to use it as a dripper as i seen in reviews that you are able to do this but i can not work out how to change it from the skwank pin to the dripper i have the extra gold plated screw for this but it dose not seem to fit correctly not sure if its faulty and cut too small or im missing something can find any videos on how to do this either any advice would be great thanks.

I mate, yes the BF pin that's pre-installed is actually in 2 sections which isn't obvious from looking at it. The standard pin you keep the top section of the BF pin so it's just the bottom section you change that's why it's a lot shorter.

 

[Matthew mcintyre]

Yeah got it sorted thanks mate.
