Wotofo Profile X RTA

Wotofo have a solid reputation when it comes to mesh rebuildable so Antony was looking forward to trying their latest offering, the Profile X RTA

Share on:

Wotofo recently got in touch to ask if I’d like to take a look at some of their latest products and when they offered up the Profile X I decided it was high time to take a fresh look at how current mesh rebuildable tanks fare.


  • 26.7 x 34.7 mm (excluding drip tip and 510)
  • 810 drip tip
  • 5ml/8ml capacity (2ml/8ml for TPD regions)
  • Flexible build deck for regular coils or mesh

Wotofo Profile X RTA unboxing

The Profile X comes in Wotofo’s customary black and green packaging, I was relieved to see that they’ve made this package much easier to open (Wotofo boxes used to be a nightmare to get open) with the RTA clearly visible in the large front window. The Profile X is available in six colours, and I was sent the gunmetal version for review, this is quite a dark gunmetal though almost bordering on a glossy black finish.

The pack-ins are quite generous with a bubble glass, tools and spare O-rings, plus five coils and cotton. There is also a brief user guide with illustrated instructions on how to build this as a mesh atomiser but curiously no instructions for the regular coils (I’m guessing that Wotofo figures that we know how to do that already!).

Wotofo Profile X RTA drip tip and 510 base

The specs say that the Profile X is a 28mm RTA, and although it is 28mm for most of its height, the base does taper off slightly to just a hair under 27mm, either way you’ll need to break out a larger mod to accommodate this. Out of the box, a straight “glass” is fitted with a 5ml capacity (2ml for TPD regions) and I was slightly disappointed to find even in this 5ml international version this is a PCTG tube rather than glass. The 8ml bubble tank is glass and given that mesh tanks have a reputation for drinking e-liquid, you may want to opt for that in any case.

Up top we have a standard 810 drip tip, and Wotofo have opted to go with the same ultra low profile resin drip tip design seen in earlier versions of the Profile. I have never liked this drip tip as it’s far too short to be practical or comfortable to use for that matter, I was worried that the slightly raised 810 platform might make it difficult to find a suitable alternative that would fit here, but most of my drip tips looked fine so I soon found a much more comfortable one to use from my collection.

Wotofo Profile X RTA airflow

The top cap uses a bayonet style fitting which only needs an eighth of a turn to remove, this does feel a bit weird in use but there is a decent amount of tension present so I’m not concerned about it coming open accidentally. This reveals two cavernous fill ports which are quite recessed into the tank, and you can actually fill the Profile X up quite a bit higher than these ports would suggest.

The airflow ring features a honeycomb structure to help smooth out the airflow, on a whim I tried it without this in place and it sounded like a jet engine in comparison! This has hard stops at the fully open and fully closed positions and can be removed for cleaning to reveal the two large cyclops airflows which are angled downwards and re-emerge inside the top of the build chamber.

Wotofo Profile X RTA build deck

This brings us down to the build deck which at first glance looks like a standard mesh deck with a spring loaded ceramic plate to help keep the cotton in contact with the coil and clamps on either side of the deck. Look closer though, and you soon realize that there’s something else going on here as this also sports a full dual coil postless deck design as well for regular coils.

Wotofo Profile X RTA coils, mesh, and wick

That would explain all the included coils and cotton in the box. You get two fused claptons (Nichrome unfortunately) and three different mesh strips (all kanthal, YAY!), plus enough cotton for each coil (two 3mm strips for the fused claptons and three 6mm strips for the mesh coils.).

Wotofo Profile X RTA builds

Both styles of builds are equally easy to install, I couldn’t find a mention of a suggested coil leg length for the fused claptons but 8mm seemed to be about right. Wicking was equally straightforward thanks to the fairly generously sized fill ports on either side of the deck. You want the cotton just to the edge of the deck with a dual coil build or cut at 45 degrees for a mesh build, and you’ll need to really fluff/thin the cotton quite a bit, particularly when using mesh.

I wasn’t expecting much from the dual coil build if I’m honest as it seems like a compromised design, so I opted to use the included Nichrome coils for once as I didn’t think that I’d be using them for long. In use however, I was pleasantly surprised by how good this was, it’s not as good as a dual coil RTA that’s been designed as such from the ground up, but it’s not that far off either. +1 point to Wotofo.

I suspect that most people who go for this will be more interested in its performance as a mesh rebuildable, and the Profile X doesn’t disappoint on this front. The flavour is great so long as you bump the wattage up and close the airflow down a tad. One aspect that frequently trips people up with mesh RTAs is the wicking, and I’m happy to report that this wicks extremely well so I had no issues and got it right on my first attempt.


  • Innovative dual use deck design
  • Easy to wick
  • Works very well as a mesh RTA


  • Straight “glass” is a PCTG tube
  • I still don’t like the stubby drip tip


If you’re a fan of mesh rebuildable, then the Wotofo Profile X should be right up your street, and if this is your first foray into mesh rebuildables and you’re worried they might not be for you, then you can rest assured that it’s actually a pretty decent dual coil RTA as well. I love stubby tanks and this suits me down to the ground, it’s even got me back into mesh rebuildables as well. In fact this and another product I’m reviewing soon are currently my two favourite mesh rebuildables to date.

Many thanks to Wotofo for sending the Profile X out for review. The Profile X is currently available for just £27.99 from our partners at Legion of Vapers in the U.K. which makes it a bit of a bargain as well so consider taking a look there if this interests you.

I was a twenty a day smoker for 25 years and like most smokers I was always going to quit "next week". Having hit my mid forties and having the usual smokers cough and difficulty with anything more than moderate exercise it was obviously time to give up the cancer sticks. I bought my first e-cigarette in 2013 when they were expensive, difficult to find and quite frankly... crap. I used it for about a week then went back to the roll ups, mark up another failed quit attempt. The fact that I had just changed jobs and was under quite a lot of stress probably didn't help. Move on to 2016 and whilst I was browsing eBay I noticed that one of the suggested items that would occasionally pop up was for a cheap e-cigarette. It looked similar to the one I'd bought 3 years earlier but it was only £5 (about 8 times cheaper than before) so I decided to give it another go on a whim. Once the kit arrived I managed to gradually replace the cigarettes with my new kit over a two month period and got into watching YouTube reviews for newer kit. My cheap and cheerful kit was replaced by a more upmarket affair, and being a noob I made a mistake once it arrived... I put in the supplied direct lung coil, this was of course a complete revelation and I haven't touched a cigarette since. Oh and I no longer spend the first five minutes of every day having a coughing fit either.
