    Getting to know the Wotofo Profile Unity RTA

    If you are not already familiar with the Profile RDA which was released sometime back in September 2018 it was the first Mesh RDA that I not only loved at the time but still use to this day. It became one of the popular RDA's back then, I know a local vape shop that was selling them like crazy. What they finally got right was a spring mechanism that kept the cotton in constant contact with the mesh, something that plagued earlier Mesh rebuildable tanks. I personally tried about 2 or 3 mesh RDA and RTA's and you could get them to work but overall they were a PITA and not worth the trouble.

    Mesh can work great though, look at how it has nearly dominated the sub-ohm tank market, nearly every new prebuilt coil coming out now has a mesh coil option.

    The Profile Unity RTA has a similar build deck to the RDA, here is the Profile RDA deck on the left, RTA on the right.

    [​IMG]

    The white grooved thing you see in the middle is spring loaded, it is there to keep your cotton snug against the mesh once installed, simple idea that works.

    The fit and finish of the tank is pretty nice and threading is smooth, no struggling to find the grooves. Half a turn and the top cap comes off to fill, would have liked bigger fill ports though.

    [​IMG]

    Airflow with all 5 holes open is pretty airy, airier than I was expecting so closed it off to 3 air holes open on each side which came me a little restriction and a bit of a flavor boost. Smooth and quiet airflow, tried all the openings and not noisy at all.

    When I used the included drip tip (no extra drip tip included which is a con) I had to open up another air hole as the included 810 drip tip has a narrow opening. Here is a pic of a normal friction fit 810 on the left, Wotofo Profile included 810 center and friction fit 510 DT on the right.

    [​IMG]

    As you can see the Wotofo provided DT has the smallest opening, smaller than a friction fit 510. Since I prefer more airflow I swapped it out after the first tankful and got a bump in flavor.

    Wotofo does provide extra o'rings, spare springs, screws and the normal whatnots including a chimney extension with taller glass for it to make it a 5ml instead of 3.5ml. You also get (2) OFRF nexMESH and (2) 6mm Agleted Cotton for wicking. No spare 3.5 or 5ml glass are included so if you break one you need to go with the other.

    Build and wick

    Installing the mesh is about as easy as it gets, just use the supplied tool to bend the mesh in advance and install it.

    [​IMG]

    Not going to bother showing the rest of that build, it was good but I found using the included Agleted Cotton it was just too thick and wicking suffered, could vape fine at about 45 watts but anything about that gave me the dreaded mesh dry hits.....cough cough cough. When I removed the build the cotton under the mesh was like a rock, too much wick. Here is a pic of the included Wotofo Agleted Cotton next to the Cotton Bacon Prime wick I used next.

    [​IMG]

    This build here was my favorite using Vandy Vape SS316L 200 Mesh and the Cotton Bacon Prime wick I show above, just use one of the included mesh as a guide to cut to the same size.

    Wotofo includes a guide on wicking in the owners manual, a nice touch as it is tricky. When feeding your cotton you want restriction, enough that it is not easy to pull out but not so much that it is tough to get through. Once in cut the cotton at an angle on both sides and uses a pointy tweezer to get it nice and fluffy.

    [​IMG]

    Additional trimming might be necessary as you do not want your wicks to reach the bottom, just peaking into the wicking slots and enough to block any juice from getting into the deck. Once your wicks are in place you can trim the top of the cotton near the mesh, just be careful not to cut the mesh. In the pic below the tucked wick on the left has had the wicks trimmed near the top, the other side still needs a little trim once the wick is tucked in.

    [​IMG]

    Care needs to be taken when installing the deck and the deck cannot be installed when on a mod or a build station as it only screws in from the bottom. There are slots in the chimney that line up with the base, best to try and get the slots close and not just spinning it around until it falls in, you can mess up your wicks. That build above lasted me a good 5 days and about 10 to 12 fill ups before I decided to take out the deck to see how the mesh was holding up.

    [​IMG]

    Look at how nice and juicy that is, performing like a champ and no problems chain vaping at 75 watts.....what dry hits, not this guy. Wasn't even gonna bother rebuilding it, still looked great and more importantly performing great after 50+ mls of juice.......Then it happened, was all cocky thinking yep, I rock and was putting the deck back in and spinning it around until the slots lined up, screwed down the deck and filled it up......oh noooooooo, leak city, lost a good ml or more of juice. Turns out the wick got snagged as I was spinning it to line up the grooves and yep, had to re-wick.....bummer.

    If you do use the included Wotofo Agleted Cotton might be wise to thin it out first. I had success using Native Wicks Platinum Blend and even Puff Organic cotton, you know, the cotton pads. If using cotton pads cut it in half, remove 1 of the top layers and stretch it out like the Scottish Roll method (google it if you don't know) your half of cotton should look like the cotton on the right after stretching.

    [​IMG]

    You can use the whole pad if you want but you then have to remove both top layers from either side. The bottom right pic shows the Puff Cotton in the center, Wotofo cotton left and Cotton Bacon Prime right.

    [​IMG]

    I got the same performance from both so might as well get 2 wicks instead of 1.

    My preferred wick is still the Cotton Bacon Prime, was able to get the highest wattage before dry hits but the other works fine up until about 65 to 70 watts.


    Any loss of flavor with the chimney extension and how does it perform?

    I ran it for a few days with the short glass at 3.5ml and it was flavorful but a bit spity. With the same build, I replaced it with the chimney extension and 5ml glass, thus making it taller. Now I am not the biggest fan of chimney extensions, the further the coil is away from your mouth the more possibility of flavor loss, that is why bubble glass is so popular, more capacity but the same distance to the coil. Using the same juice the first thing I noticed with the extension in place is a big reduction in how spity it was. Not like your drinking your juice spity but more of a moist vape, the extension made it drier. I do find a moist vape to be more flavorful and that was the case here but with the extension, I found I didn't mind the slight flavor loss for and a decrease in spit back. Still found it to be a flavorful tank without having to smack your lips so much from the sugar lips.

    Really doesn't add too much height, maybe about 2mm taller or so.

    [​IMG]

    Now compared to a normal RTA using normal coils it is different just like the Profile RDA is different from a traditional RDA. If you don't like the Profile RDA then you probably won't like the Profile RTA, if you love the RDA then yeah, the RTA is probably already in your hands. The wicking is more tricky with the Profile RTA over the RDA though, I do wish they would have added a squonk option to the RTA just like the RDA, push juice from under the cotton would have been great. With the juice having to feed into a thick wick from the sides rather than the bottom makes wicking that much more critical.

    I won't be giving up any of my favorite normal coil RTA's anytime soon and replacing them with a squadron of Profile RTA's. I do feel they both have their place in my rotation though. I have been enjoying my Profile RTA on my single 21700 mods, usually with the Vandy Vape SS316L 200 mesh in TC. Doesn't take a lot of power to spark up the mesh which means I can go for a while on a single 21700.

    [​IMG]

    Of course, I could also go all day with a larger mod.

    [​IMG]

    It is more of a tame vape then my usual dual coil RTA's but the flavor is good and once you get the hang of it quick to build and wick. The downside is how much wick you have to use but the build should last for a while unless you do like me and get all cocky when re-installing the deck.

    Pros:

    • Installing the mesh is about as easy as it gets
    • Very good flavor
    • Smooth threading
    • Includes everything needed for your first build
    • Can increase juice capacity from 3.5ml to 5ml without a bubble glass
    • Easy open top, half turn and you're ready to fill


    Cons:

    • Included 810 drip tip has a small opening and no extra drip tip included
    • Tricky to wick but once you get it easy to re-wick
    • Can be spity in 3.5ml, the 5ml extension helps with that but with a slight loss in flavor
    • Definitely not going to be for everyone, different enough from a standard RTA that some may not like
    • Care needs to be taken when installing the deck to not shift the wicks
    • Fill ports a little too narrow making it slower to fill, not a huge deal but I am impatient

    Final Thoughts

    Do you love the Profile RDA? If so then get this, just don't expect it to be as easy to wick. Did you think the Profile RDA was an overhyped POS? Then skip the Profile Unity RTA, I doubt it will change your mind. The vape you get from a mesh rebuildable is different enough that I can completely understand why some will discard it and stick with there normal RDA and RTA's. Some say it is dry and yeah, it can be. It definitely is not as rowdy as an RDA/RTA with a pair of lava spitting Aliens in it, it is not supposed to be. It is not for high powered vapers, at best it can go up to 80 watts with a great wick job but is more comfortable in the 50 to 70 watt range. I do enjoy the Profile Untiy RTA but not as much as the Profile RDA, the RDA just has me hooked.

    As I was gathering my thought to write my final thoughts it dawned on me that I have had the Profile RDA for close to 8 months now and still use it at least 4 times a week on a squonk mod, it has never left my rotation. I then began to think if the new Profile Unity RTA will also get the same amount if use and my first thought is no. I will use it from time to time, primarily on my single 21700 mods as overall they match up well but I have a number of single coil RTA's which I enjoy just as much on my single battery mods and some even more.

    I hope this helps you make an informed decision and if you want more info you can check out the product page, they have a very interesting video there as well. Wotofo Profile Unity RTA

    Update:

    Just rewicked the Profile RTA using rayon. Ran my tails a little lower and used a bit more than I would with cotton. So far this rayon is wicking like a champ, I think I have enough for 1 more wick.......or 1 million [​IMG]

    Awesome review! So awesome I’m going to ask a question in an attempt to extend it a little.

    I was reading a thread about the unity and it appears it has a second feature I’ve never seen in another device: a second set of juice ports.

    Apparently according to the company animated video there are not only juice ports at the bottom for the wick ends, but also a small set just above the air inlet. This is odd. That juice should do nothing but run down the sides of the tank and mess with the air inlet. Engineers are smart puppies as a rule though and those ports cost extra machining to put in, so they must do something. The question is what? Add extra flavor by simply getting more juice into the air perhaps using the inlet airflow like a carburetor Venturi? I’m terribly curious. The only way that I can think of to do that is to plug them up temporarily and see what happens. I don’t have a unity though and my profile is still in the mail. I have no ability to test. You do though. Feel like a second review? :D

    Thanks, I appreciate it.

    Are you referring to the 2 holes on either side? There not actually air holes but juice ports., right on top of the juice inlet that feeds the bottom of the wicks. As I understand it they added the extra juice ports so that it wicks from not just the bottom of the wick tails but also from the top of the wicks. There is a ton of wicking that needs to get saturated.

    I did try to get a pic of the inside but none of my pics came out good.

    I just read another review from friend and it was a tricky wick for him as well. Once you get it it becomes a lot easier to wick, vaping on it today with my fresh rayon wick job and pleased. I do feel there is definite room for improvement though but mesh is heading in the right direction, best mesh RTA to date.

    Cool! The juice should just dribble out those ports though not squirt. Unless the wick is touching the sides of the tank it shouldn’t do much.

    I’ve got a aromamizer plus parallel deck with an iffy PEEK insulator I’m lightheartedly hoping to take apart as soon as I get some other fires put out. I was thinking when I did it I could cut a slot between the posts and fit a mesh coil on it. Maybe. If I get to it at all :/ my life is getting more complicated. Anyway such a thing would not have the secondary juice ports. By rights the vape should be bone dry then. Especially with the big 10ml tank on it. Bah. I really want to find out now. If the dribble isn’t touching the wick from the top but running over the air inlet ports producing a Venturi effect there should be ways to improve it.

    The challenge with the Unity is to saturate the wick in a timely fashion otherwise you may suffer from dry hits. There is A LOT of cotton to saturate which will grant a high flow of juice. There are the bottom juice ports, like every other RTA, that rely on capillary action in order to get the juice to the mesh. The engineers obviously felt this was not enough. So they implemented additional upper juice ports that contributes to saturating the wick. These are located above the lower ports, but still within the lower section of the tank. If the tank is filled beyond these ports, juice will flow out of them, not trickle past them. The wick is pressed up against these ports which should mitigate flooding should they not be too thin. They do not contribute to flavour, but allow enough flow of juice to mitigate dry burns.

    @mjag – nice review. As I am sure you know, every RTA comes with its own unique challenge when it comes to wicking properly. I wouldn’t say the Unity is any more difficult, but just different than the norm should you follow the instructions. TBH, I thought the Geekvape Zeus Dual to be more problematic.

    I have toyed with different wicking and currently using 3/4 of a Muji pad with their outer layers removed. I found half a pad of Muji to be a tad too little with the RDA – a full pad, although worked well, was not necessary.

    The separation, aka, Scottish Fold technique is not really necessary but certainly does not hurt. But you should not roll the pad tight. Pressing my scissors up against the juice guard on the deck, I cut the wick perpendicular, then with a blunt object, fluff, not thin, out the ends to remove any compression due to the cut. Should look like a nice fluffy white bow tie! I tuck a small portion of the lower half of the wick into the bottom juice ports, ensuring they are not tightly packed in. Use your tweezers to check. They extend about halfway down. The rest I leave in place. She wicks like a champ at 60 watts, and I have been chain vaping this RTA like it was stolen!!! Next time I rewick I will take a picture and share with the class.

    Haven’t tried Rayon in the Unity yet – perhaps that will be my next experiment.

    If they’re touching they’re touching. I won’t be able to make a concave shaped plunger anyway. I was thinking a piece of ceramic rod. Should make for a U shaped wick. Less cotton at least. Might ruin the whole thing. I’ll have to get it apart AND replace an unbuyable PEEK insulator if it’s bad first though. (Shapeways maybe. They can print PEEK) THEN I’d have to cut the slots AND get it back together again, which is the bit I most commonly mess up. The putting it back together again part is where I failed science. One doesn’t need the math in biology (I also don’t have the math) but you still gotta make labs work. I get to blow 20 inches of snow tomorrow so my tenants can get to work. Stay in school kids.

    If what is touching? I am going to take a wild guess you are talking about your Aromamizer cause I have no idea on concave plungers, ceramic rods and printed PEEK.

    How about instead of throwing money into a uncertain project with a unknown outcome, invest it in a fully functional Profile Unity RTA?

    What would be touching is the wick and the second juice vent.
    The profile and the unity both have concave plungers that press the wick against the mesh. I can’t make one. I can cut a piece off a ceramic rod though.
    I can’t invest in a unity because my April vape budget got used up already buying the profile. And a kryptonite 454 big block I’m going to have to core out somehow if I want to squonk it which I do. I still got a shed and too many tools though.

    The wick does touch the side of the tank, those too juice ports are meant to feed the top of the wicks. I cant say for positive they are completely covered but based on how it vapes would say they are.

    This is why you need to be careful when installing the deck into the chimney, too much wiggling around and you can dislodge your wicks.

    That would be way interesting if you can install a mesh into the Aromamizer Plus......love love love that tank. I have seen people ask SC in the SC fan FB page about mesh, they said they are looking into it. I would love a SC mesh tank, they generally get things right.

    60 watts isn't a problem but I do like a higher wattage and the wick I showed got me to 75 watts of chain vaping happiness. I do torture test stuff and I got it to go 12 puffs with each puff lasting 3 to 4 seconds, could have went longer but I was using nic and didn't want to get too much of a buzz. Sorta of wanted to point out what the max it would do, can do 80 watts but if chain vaping at 3 to 4 second puffs started to get a little dry on the 4th puff.

    That would be great if you could share you build pics, the more help the better and thank you for adding your wisdom

    What would the ceramic rod do? Digiflavour Mesh does not have a spring loaded base, just a flat deck.

    How are you planning to fix a mesh strip to a deck build for coils?

    I have put the Unity through its paces at 70(ish) watts, still wicked fine but much prefer the vape at 60. With the RDA I do not go above 65 to 70 watts – anything higher I feel it get unruly. The nexMESH is only rated to 70 watts if you hold any value to that rating (I never do!)

    You can see with this cutaway the upper juice flow sits just above the wick guard where the cotton will be thick assuming one has not trimmed it back too much. My first build I did have an issue with flooding which led to a slight leak out the airflow - but only when filling the RTA and screwing the cap back on. You could tell there was a pressure change for the juice level dropped once the cap was tightened. But pulling the RTA apart and reassembling it rectified the problem – I never touched the wicks. I am guessing I did not screw in the deck in all the way, WHICH, theoretically would have put the upper juice ports higher above the deck. That’s my theory anyways!

    That is a great cutaway to show the too wick ports.

    Never tried high watt vaping with the nexMESH, it is good but I just fell hard for the Vandy Vape 200 mesh. The 75 to 80 watt tests I did was with the VV 200 mesh, I know it can take higher watts based on my Profile RDA experience. With the RDA I can put it on my squonk mechs and it pulls 100 watts with no problems.

    It is getting late but will subscribe to that thread you posted and read it this week....thanks
