Is The Themis RTA From Digiflavour Guilty or Not Guilty Of Being a Great Vape?
The Digiflavor Themis 25mm 5ml RTA is a big chunky tank that is inspired by the extremely popular Zeus RTA from sister company GeekVape.
Digiflavor make no bones about this being pretty much the Zeus 2 so to speak and it certainly shares similar traits especially the top to bottom airflow and postless deck.
As to whether they’ve improved on that we shall see especially as following my review of the Geekvape Zeus RTA I actually and for once – opened my wallet and bought another lol.
Themis is the Greek Goddess best known for being the blindfolded lady we see above the scales of justice in anything court and legal related.
So let’s see what sentence I pass on this one.
The Themis was sent to me for the purpose of this review – as always my thoughts and opinions are my own.
Inside the Box
I received mine in the sample packaging box – yours may be differently packaged.
Inside you’ll find:
- 1 x RTA
- 1 x Glass Tube
- 1 x 510 Drip Tip
- 1 x Accessory Bag
- 1 x English User Manual
Digiflavor Themis RTA Specs
- Stainless steel construction;
- 510 threading connection;
- Gold plated positive pin;
- Diameter: 27mm (overall), 25mm (bottom);
- Interchangeable build deck (Dual Coil Version);
- Compatible with both dual and single coil builds;
- Leak-proof top to bottom airflow system;
- Quick access top cap for convenience
I was sent the dual coil version which can also be used as a single coil and a mesh version is also available.
So when choosing which of the Digiflavor Themis RTA’s to buy double check you’re getting the right one!
Sadly I can’t comment on the mesh version.
OK as I’ve explained GeekVape and Digiflavor are sister companies and the Themis is ‘inspired’ by the Zeus RTA.
And once again this is touted as ‘leakproof’ – given I found the Zeus didn’t leak at all we shall see if the Themis matches this claim.
On the dual/single coil post-less deck I’ve been using we have a cut-down version of the Zeus airflow posts but it is still a top to bottom air feed set-up.
It’s a 25mm tank that slightly bulges out above the base and is certainly longer and fatter than the Zeus – 27mm at the waist – so this is a big boy!
It’s a dual cyclops airflow design with a stopper and it mirrors both sides.
It has an 810 delrin drip tip that once again sits over a raised nipple just like the Zeus.
Other 810s I’ve tried do fit though they sit flush on raised edge adding even more height to the tank – a 510 adaptor is also included.
It’s a convenient top-fill with the cap a bayonet style fitting – half twist on and off.
Despite it’s size it is still only a 5ml capacity and I’m not sure a 2ml EU version is available – however a few UK websites I’ve looked at are stocking only the 5ml – maybe there’s a bung in those versions you can remove?
Build and Design Quality
I’ve never used a badly built Digiflavor product and the Themis is just as good build wise.
The threads took a couple of fills to loosen up but are now lubed and smooth as you like.
Breaking the Themis down into its components is straightforward and there are a lot of moving parts.
The deck is pulled from the tank by the 510 pin and is clean and relatively easy to build on – more on that later.
Design wise it’s a good looking with very clean lines but as I’ve said it is a 25mm that expands at the waist [like me] to 27mm and is one of the largest RTAs I’ve used.
To get to the deck you unscrew the base ring and pull it away via the 510 pin.
The deck is housed in a stainless steel shell inside the glass with two notches you need to line up with the airflow posts on the deck before pushing it back in place.
The cutout T shapes are reminiscent of the Transformers logo and Themis is engraved or stamped inconspicuously onto the base ring only adding to the clean looks.
So it’s certainly a stunning looking RTA – so how is it to build and vape on?
How Does the Digiflavor Themis RTA Perform?
The Zeus was single coil and the Themis is a little more adaptable as I’ve already stated.
And a quick reminder I haven’t got my hands on a mesh version but have used it in both single and dual coil mode.
The Build Deck
It’s a straightforward enough post less deck – not my preferred – but it is what it is.
The post screws are a bit of an issue for me at least.
They are flatheads and tucked underneath the post holes meaning you have quite a distance to get to them.
Once the screwdriver is in the ‘housing’ – you are quite blind and it can be fiddly lining everything up to get them out.
They aren’t the best or worse screws I’ve used but it can be a bit hit and miss if you don’t have the exact size screwdriver – I found using the included tri-tool even more fiddly.
Given we have a much shorter set of airflow posts – only 3 colander style holes on each – your coil positioning is relatively straight forward – I found bang in the centre of the posts was perfect.
Wicking is a doddle with shared juice ports in dual coil – just make sure your tails are well combed out and don’t pack those ports – keep everything loose and fluffy a teeny bit off the bottom to avoid dry hits.
Single Coil Mode
OK you need to build your coil at an angle and then straighten once tightened down and follow the same wicking – loose fluffy and not tightly packed.
I used a GeekVape Fused Clapton Coil at 0.25ohm wicked with Fuzz and began at a steady 53.5w vaping on Lemon Refresh from the Chicken Shop – delicious stuff!
Flavour was the first surprise and given I have been using RDAs a lot more lately I was impressed with the taste but not blown away.
Cranked up to 77w and the unlike the Zeus which got hot over 50w the Themis stayed warm and the flavour popped considerably.
For fun and science I had a go at 100w and obviously things warmed up but still not unbearably hot and the flavour was there but maybe just maybe a little muted.
Cloud production even on the lower wattage was very good indeed and impressive for a single coil at 100w.
Dual Coil Mode
Oh boy this is when the Themis comes to life and then some!
I used a pair of basic 0.5 ohm Claptons which gave me a 0.29 ohm vape.
I kicked off at 57w and immediately the improvement in flavour was obvious – as was the cloud production.
At 77.7w I found my sweet spot with rich deep flavour notes and dense aromatic clouds for days and my perfect vape temperature.
Once again I hit the 100w and once again the Themis coped without a hint of a burning taste and whilst a little too warm for me it was manageable.
Trust me the Digiflavor Themis RTA absolutely shines in dual coil mode and I reckon it can take some serious builds and wattage – unlike the Zeus.
- 5ml top fill
- 25mm base
- Multi deck options
- Single and Dual coil
- Tremendous flavour
- Superb clouds
- Leak proof design
- 810 drip tip compatible
- Copes with high wattage
- Thirsty! It loves to drink that juice in dual coil mode
- It is a large tank!
- No coils included
Final Review Verdict
I loved the Zeus – sure the flavour wasn’t as good as some RTAs out there but as an out and about device it was the lack of leaking I enjoyed.
The Themis hasn’t leaked on me once including leaving it on its side on kitchen paper over night – OK maybe a tiny drop but we’re talking miniscule!
Simply put the Themis beats the Zeus in every aspect except maybe getting to those post screws.
I’d seriously not bother with single coil mode – the flavour is OK but trust me in dual coil this thing excels – the flavour is superb and better than any of the other RTAs I’ve used.
The top to bottom airflow works extremely well – the AFC is maybe a tad tight even now after 2 weeks plus of use but it isn’t moving once you find your sweet spot!
Size wise it’s a big bugger and will definitely look daft and top heavy on smaller mods so perfect for those of you who like their devices on the big and chunky size.
So flavour wise I can’t fault it – it will also please the cloud chasers however especially over 70w in dual coil mode it will drink your juice.
So my overall verdict is the Digiflavor Themis RTA is most definitely guilty of giving off great flavour and it would be criminal for you to not free this one from your favourite vape shop cupboard 😉
