Introduction: Hermetic RDA by Blitz and Suck My Mod

Today, we take a look at the Blitz Hermetic RDA, a collaboration with Suck My Mod.

Whilst most will recognise Blitz instantly, unless you follow YouTube reviewers, you may not instantly know Suck My Mod. Suck My Mod is a US reviewer with 220k plus subscribers and well known within the Vape Reviewer community. They aren’t new to collabs, they also worked with Wotofo on the excellent Wotofo Serpent SMM RTA. So we have high hopes here!blitz hermatic rda review
The Hermetic RDA is 22mm with a reported leak resistant bottom airflow with bridged airflow technology.

At first glance, you would be right if you thought you had seen this design before, or something very similar in the form of the Ghoul RDA. Lets see if the Hermetic RDA offers enough to set it apart from the rest.

As always, the Hermetic RDA was sent to me direct for this review. I will, as always give my own, honest opinion of this product after a lengthy testing period.

Design and Build Quality

The Blitz Hermetic RDA is very well built and machined. On looking in the top cap, you can see the quality from the off, nice thick walled and there are no sharp edges, residual oil or loose shards to be seen.

The design on the outside of the top cap is, in SMM’s own words “an Alchemy” design. The design itself may not in itself be magic, that’s left for the deck design.

Now, though the Hermetic RDA is similar in design, it is also quite different. That’s to say, the airflow is singular and has a bridged airflow design to direct the air directly to the bottom of the coil.blitz hermetic rda

Depth of Juice Well

The juice well for this single coil RDA is rather quite large measuring to its lowest point a rather deep 7mm.

You will be very hard pushed indeed to over squonk or over drip. In my time testing the Hermetic RDA, I over dripped once and that was only a couple of dribbles from the air flow.

The Blitz Hermetic RDA has a single ceramic clamp system.

The coil legs are placed at both sides of the post whilst positioning the coil above the deck on a coil jig in the recessed slots.

The coil is tightened down by a single Philips head screw sat in the centre of the ceramic clamp.Coil build on hermetic rda blitz

I opted for a Framed Stapled Clapton with an inner diameter of 3mm but if you opt for a 4mm inner diameter coil, there is plenty of room for this.

There is no need at all to measure your coil leg length as they protrude out of the back of the ceramic clamps enabling you to cut the excess without a problem at all.

Air Flow

The airflow on the Hermetic RDA comes from the rear of the RDA. At first, moving from dual airflow devices, it can seem a little peculiar but soon becomes “normal”.

The airflow is a little turbulent with some noise when you are vaping. That said, it really is nothing ear splitting. The airflow, although a tad turbulent, still gives a smooth vaping experience.

The air comes into the airflow at a slight downward angle, along then up through the Bridged Airflow thus hitting directly underneath the coil maximising the flavour from this RDA.

How does the Blitz Hermetic RDA Perform?

The Hermetic is a single coil, sleek designed RDA but how does it perform, and does it stand out from the crowd?blitz hermetic rda on mod

Well, I have been using the Hermetic RDA as a squonking and dripping RDA in equal measures and neither out performs the other. Each of us has our own way of vaping and it is good to note that which ever way you go, it won’t affect the way this RDA performs.

This is mainly due to the fact that your single coil is placed in the same position how ever you vape this RDA. Some RDA’s give out different flavour or produce differing cloud production depending on the coil placement. You are guided as to where you place the coils in the Hermetic RDA so as long as you use the same type coils, you will get the same results each time.

The flavour from the Hermetic RDA is very good though I wouldn’t say it’s mind blowing. I do feel that if the depth of the well was shortened and the overall height of the Hermetic RDA was shortened then you would get slightly better flavour.

The cloud production from the RDA is ok but, this is a 22mm single coil RDA so you can forgive it for that .


  • Well priced
  • Guided coil placement for beginners
  • Large Juice Well
  • Quality design
  • Airflow placement


  • None

Final Verdict

You may notice looking above, I have no Cons for the Blitz Hermetic RDA. I’ve searched hard just to even find one and I can not realistically do so.

This single coil 22mm RDA is a very strong RDA with good flavour and cloud production but I feel there isn’t anything that makes it stand out from the crowd. If you put 10 RDA’s on a table in front of me, I feel the Hermetic RDA would be lost as there isn’t enough from this to make it stand out.

I also feel that lowering the profile of the Hermetic RDA would have stepped up the flavour and moved it up another notch, slightly raising it’s pretty little head above others and becoming more noticeable.

Hello all. My name is Ian and I'm a 47 year old Care Worker, husband and father. My Youtube Vape channel was started in 2018 and has 81,000 views and counting. I started my vaping lifestyle back in 2014 when me and my wife both decided to pack in the cigarettes. It wasn't an easy task at first as I had smoked since the age of 15, so, that would make nearly 30 years on the dreaded cigarettes. After around six months switching between cigarettes and vaping, I finally kicked the habit and became a full time vaper. Vaping is a way out of smoking, not only does it save you money, it may, one day, save your life. For anyone wanting to stop smoking cigarettes, all I would say is stick with it. Nothing in life comes easy, believe me when I say, you will soon start feeling the benefits both in monetary terms and above all, feel healthier. Happy vaping
