MURAMASA RDTA REVIEW

MURAMASA RDTA REVIEW

Please take into account when reading this review that the Muramasa like its predecessor the Yokozuna Sub-Ohm Tank has been primarily designed to use with mini devices hence their size!

Dating back to the Muramachi period in Japan’s history between the 14th and 16th centuries A.D lived a master swordsmith by the name of Muramasa Sengo. Portrayed as a master craftsman of his era, he dedicated his life’s work into producing the finest forged samurai swords, putting his heart and soul into the forging and tempering of the steel that they were created from.

So the name Muramasa, which has become a thing of legend, synonymous with the taking of lives, has now been adopted to one which I hope will play a part in the saving of lives – thanks to the dedication of a new breed of master craftsman from MarsTeam Japan.

Their latest and first RDTA incorporates the name Muramasa with the same dedication and willingness to be the best at their chosen profession, not only producing some original design concepts, but also in the machining process which they hope will live up to the name. So, let’s take a closer look and find out.

For the purpose of conducting this review, I have used a selection of different E-Liquids from Dark Market and Confection. I have also used the latest SMOK Alien plus the iPV 6X devices to test it.

For consumers based in the UK & Europe, these Premium E-Liquids can now be purchased by following this Link.

E-Liquids may contain Diacetyl (DA) and acetyl Propionyl (AP) or other carcinogenic ingredients or disease-causing substances, so please be aware of this and seek medical advice before using any of the products used in my reviews.

People can suffer from allergies to chemicals that may be present in the makeup of certain types of E-liquids or produced in their vapour. People can become sensitive to, or even allergic to Nickel or Titanium used in Temperature Controlled designed coils.

Once Again, please be aware of this and seek medical advice before using any of the products used in my reviews. Also, check with your E-liquid supplier or the equipment manufacturers directly before purchase and use.

You might find this range of calculators provided by Steam Engine particularly useful, so thank you to Lars for allowing me to include them in my reviews. These calculators are currently under development, and the information that they contain may change at any time without notice. Please read the How It Works section for a more in-depth understanding.

Please make sure you are using the supplied charging cable for this device, and always remember, SAFETY FIRST.

Operation

The Muramasa although small offers you two types of setup depending on whether you prefer a restricted airflow for mouth to lung vaping preferred by the ex-smoker, or alternatively, wide open for a direct Lung inhale which is more commonly associated with Sub Ohm vaping.

When you remove the tank from the box for the first time you will notice the stainless steel top cap has three airflow channels of varying sizes forming a triangular shape cut into it on both sides.

Situated beneath this is the exact same and aligned combination laser cut into the Polyether Imide allowing you to either directly align them for a fully open draw or, rotate the top cap to close off the airflow for a more restricted and tighter draw, depending on your personal preference.

You can expect to experience a more flavoursome vape with a restricted airflow but at the same time less vapour production. Equally, the reverse will produce more vapour and less flavour.

To help increase the flavour in the unrestricted alignment, position your coils towards the top of the airflow inlets and closer to the outer chamber wall.

Using smaller diameter coils will allow the air to flow more easily around them helping to increase the flavour production. A shorter flatter top cap will also help, closing the distance between the coils and the drip tip.

Removing the outer top cap and screwing in the additional wide bore chuff cap to the inner polyether Imide chamber automatically reduces the overall height between the coils and the mouthpiece for you (all clever stuff!) thus improving the flavour production when the Muramasa is setup in cloud mode.

To Access the gold plated build deck and screws remove the gold coloured polyether Imide chamber wall which is held into place by a single O-ring.

The deck itself is just about as easy to build on as you can get. Very open and accessible in a two post design with large diameter single post holes with flat head screws positioned at the top, making it far easier to attach and secure the coils into place.

You will notice that there are four wicking holes (two on either side) cut into the base of the deck and situated in line with the positioning of the coils, two of which are blocked off for a single coil build.

Unscrewing the gold plated deck gives you access to the Delrin plug underneath which can be removed for dual coil builds.

You may have noticed a gap around the circumference of the deck which is used for filling the 2ml juice well with E-Liquid. This is yet another fine example of the level of detail that has gone into designing the Muramasa RDTA.

Building

To start off with loosen the flat headed screws on the top of both posts. Insert the coil/coils making sure one end connects to the positive post and the other end is attached to the negative post. Tighten the screws back up to secure each coil into place removing any excess wire with your cutters.

Repeat this process on the opposite side with a dual coil build and you should now have both positioned ready to insert the organic cotton. You can use an Allen key to align the coil/coils if they are not yet in a horizontal position.

Remember at this point to make sure that the coils are not directly touching either of the gold-plated posts or could come into contact with the 304 stainless steel outer casing when it is replaced causing a short.

Also, make sure each of the coils is centred over both bottom airflow inlets for maximum vapour production and the Delrin plug is removed for dual coil builds or inserted for single coil builds only.

Use your ohm’s metre to check the resistance of your build and check for shorts before test firing and using your build.

Next, attach the open deck to your device and pulse the coils using ceramic tweezers if required to make any small adjustments to the spacing of each coil in order to remove any hotspots, looking for an even glow across each of the coils surface areas.

Cut one or two strips of organic cotton to length depending on whether you have chosen to use either one or two coils in your build and insert these through each coil making sure you have allowed enough at both ends to fit into the juice wells below.

And finally, apply your e-liquid making sure the coil/coils and the organic cotton are coated sufficiently, filling the 2ml juice well up from around the side of the deck.

Replace the outer casing carefully once again, making sure that neither of the coils is touching either the posts or outer wall, as I have already mentioned and you should be just about ready to go.

Conclusion

This is another gorgeous piece from MarsTeam JP that is most certainly worth considering if you have a preference for petite RDTA’s that perform well, are original in their design, and look good. Very good indeed, especially for the price.

The first thing that struck me about the Muramasa was its aesthetically pleasing looks and the quality of the machining, which was what I would have expected for an atomiser that costs far more than this one.

They say that the devil is in the detail but in this case, it’s more in the design concept when you consider that the engineers have incorporated two vaping styles into one RDTA, making a very good job of it on both counts.

Both the machining and threading are of a very good standard, more so than the price would tend to suggest.

Having the option to use the Muramasa in two separate configurations to suit the style of vaping you prefer is not only clever but original.

Building on the gold plated deck which serves to improve electrical conductivity is simplicity itself  and a added bonus to the newcomer and experienced vaper alike. The inclusion of another two post holes of the same diameter would be a nice touch keeping in line with what has now become an industry standard. This would be possible on a 25-28mm version also. Just a thought!

The ability to close off one side of the top airflow system similar to the one used with the Mutation X 4VS would be of immense value for single coil builds, so I hope a separate replacement part can be offered as a replacement for the current version.

Two other minor details relate to the threading on the wide bore drip tip which would benefit from more threading as it appears to me to be a little on the short side. And secondly, an additional O-ring on the standard drip tip to make the fitting a little bit more secure.

I did not receive a screwdriver in the spare parts bag which may very well have been included on the final production release but I thought I’d mention it just in case.

So to sum up the Muramasa RDTA for you, it’s a steal at the price, offering extremely good all round performance and most definitely one worth adding to your collection.

Expected price range is set to be around the £17.00 or $20.00 mark.
