Recently it seems like there has been a bit of a spike in the amount of square shaped Rebuild-able Dripping Atomizer’s coming to market, it seems to be a growing popular trend at the moment, as it seems manufacturers are looking at ways to capitalize on the huge popularity of box mods by designing RDA’s that sit squarely (no pun intended) on them, to provide a better fit than the standard cylindrical based atomizer.
Tobeco are looking to jump on this with the release of the Tobeco Rubik RDA, a genuine RDA designed to sit perfectly on box mods, whilst providing an offbeat design and unique top and bottom airflow. Lets have a look at this unique design from Tobeco!
Kit Contents
- 1 Rubik RDA
- 6 O-Rings
- 3 Screws
- 1 Gift Box
The Rubik RDA is housed in a pretty cool cardboard box with a rubik’s cube style design on the outer, everything about this RDA is very boxy! No blue screwdriver included here to add to your collection either…
Rubik RDA Set Up
Top marks to Tobeco for the design of the build deck, nice, easy and user friendly! It’s easy to get to as the top cap slides on and off easily, and securely at the same time.
The build deck is comprised of a three post set up with large Phillips screws and large 2.5mm post holes with plenty of room to build on. Looking at the deck you have a reasonably deep juice well, and either side you will find the 8mm cyclops under coil airflow slots.
Building on the deck of the Rubik RDA is a breeze, you have a lot of room to play around with here. The Phillips head screws are thick, and thankfully they do not come screwed into the posts too tightly, and are adjustable with ease, the post holes measure in at 2.5mm so there is plenty of room for large wire thicknesses to fit through. It’s very forgiving.
For my build, I went with 8 wraps of 0.42mm kanthal with a 2.5mm internal diameter for 0.46ohms, and made sure I adjusted my coils so they sat over the airflow slots for maximum flavor.
It was so quick and simple to set up, 0.42mm kanthal is relatively thick but I had no issues feeding the coil legs into and through the post holes, and the large Phillips screws trapped the coil legs down securely.
Specs
- Unique Rubik’s cube inspired design
- Top and bottom airflow
- 8mm cyclops airflow slits providing under coil airflow to enhance flavour
- 3 post design with large 2.5mm post holes
- Adjustable airflow
- Wide bore drip tip included
- 510 threaded connector
How Does The Rubik Perform?
With the airflow, it almost seems like it is a little throttled for me, the airflow is drawn from the top and bottom of the Rubik RDA, my first thoughts were that the bottom airflow would be blocked off by the top cap when on a mod, but if you look at the bottom of the Rubik RDA you will notice some tiny slots where the air is drawn from. 
These slots I believe could do with being a little wider to allow for more airflow to be drawn from the bottom, as when you close off the top cap airflow and just use the bottom airflow for flavor the draw to me seems very restricted.
The Rubik RDA, as with most RDA’s offering under coil airflow, is prone to leaks through the airflow slits on the deck, so you need to ensure you wick carefully to minimize this. I found that dripping your juice directly onto the posts and letting the wick soak it up negated the leaking somewhat.
The top cap airflow I could only adjust by removing the wide bore drip tip and placing this over the airflow slots to my desired setting, whenever I tried to twist the drip tip I ended up twisting the entire RDA and changing my bottom airflow setting.
Overall, the Tobeco RDA does provide some great flavor through the large airflow slots on the base of the deck underneath your coils, but cloud chasers will be left disappointed as this really isn’t set up for clouds in my opinion, despite the potential, it’s more of a flavour focused RDA.
PEEK insulators are used and they seem quite solid to me, so I believe that the Rubik RDA has no problems handling low resistance builds.
Final Review Verdict
If the different cube sections of the Tobeco Rubik RDA actually spun as well, that would have opened up a wealth of different airflow options that could potentially make for an amazing RDA boasting arguably the most customize-able airflow on the market. Potentially something to think of if Tobeco decide to release a version 2!
Overall, it is a little hit and miss. There is some good flavor production, better than average, but I feel with the under coil airflow it could be better. I also expected a bit more from the airflow in terms of vapor production, it seems a little limited. It looks bloody cool though, so if you are a vaper that want’s something a little unique this could very well be for you!
The Good
- Build deck is a dream to build on
- Big posts with larger than average post holes
- Unique design
- Good flavour production
- Suits box mods surprisingly well
- It’s cheap- available for under £20
The Not So Good
- Airflow options seem quite limited
- Not one for the cloud chasers
- It’s pretty hefty
- Only suits box mods with squared off edges
- Edges on the RDA are quite sharp
