Fuel the Mulus

Aspire have been a massive part of the MTL scene for some time now and have developed various ways of staying relevent in this sector. They have focused consistently on research and design, which has given them an established market and ongoing consumers. Here the Mulus awaits…

Out of the Box

The kit comes in four different designs, all black, red, blue and green, all of which are beautifully finished with resin panels. You can get the black panels too if you prefer. The retail price comes in at $50 or £45, making this very competitive.

The pod carries 4.2ml liquid, which is a huge amount in a device of this size. 

There are loads of spare o-rings, along with four coils, two from the Tigon range and two from the Nautilus Range. All together you get a 0.4Ω Tigon coil, a 1.2Ω Tigon coil, a 1.8Ω Nautilus BVC coil and a Nautilus 0.7Ω 2S mesh coil.

As always, at the bottom of the box is the user manuals along with a warranty card.

The Build

The way this device is filled is through a little rubber bung which could be developed to be much easier as it can be a bit of a pain to get right and not get an airlock. The coil switching process is easy with a push and pull fit. The overall size is 94x50x24mm, nice and tidy.

The pod is compact and packs some great features. The pod can be changed from wattage, bypass and voltage, which is awesome, and it can reach a massive 80W which may be slightly too much for some coils and is more ideal for an RBA. It will be quite interesting to see what they come out with for the RBA and how the bridge will work in daily use. 

One thing to note, the higher up in wattage you go, the faster you will drain the battery. For me, at 25W it lasted about two days, so very decent.

BVC Single Coil - 1.8Ω

This is a good fit for MTL vaping so if that is your vape style, then this is the choice. The airflow was fully open and the draw was really good. The flavour was really good and I was impressed with how it performed. For me, MTL is not my chosen option but I thought it would be good to try this for the sake of this review.

2S Mesh Coil - 0.7Ω

Throughout my time testing out the mesh coil, it’s been a great little coil and I can say it has performed well and lasted a while. I used nicsalts, 50/50 and 70//30. There has been no change in power, flavour production and it is still going strong. It had about 60ml of liquid go through it so wow! The flavour was banging and much more prominent than the single coils 1.8Ω. This gave a restricted DTL vape and worked a treat. I used both coils for the month and they are still both working great!

Tigon Coil - 0.4Ω

So far this coil has been great with nice flavour. I upped the power to about 30W. It tasted great but then I had a slight dry hit. It is still going strong after 30ml of liquid. I would be more inclined to go for the Nautilus coils as they are much stronger and more consistent.

Aspire Mulus tank and mod

When priming the cotton, it took about ten minutes. It should have a decent time to soak up so that it doesn’t damage the coil. I made sure that it was left for a long while so that the flavour was on point and I didn't start with any dry hits. 

Aspire Mulus side view


  • Lovely design finishes
  • Compact
  • Good airflow
  • Amazing flavour and clouds
  • Awesome size
  • Refillable pods
  • Replaceable coils


  • Leaking if left too long
  • Some spit back
  • liquid level is hard to decipher


Wow oh wow! I’m usually a big squonker or regulated mod kind of vaper, but since using this, I have adapted to pod mods and AIOs. This made me purchase a premium device because I was so impressed with how this performed. It is one of my go too devices and I will be using this on a regular basis. It's small, compact and goes in the pocket without worrying about trouser pocket sag or weight.

Now would I buy it? 100% go for it! This is a must have device in your vape collection.

My first mod kit was the majesty back in January 2018 where I started to try different hands-on with building all self-taught, understanding the difference behind them all. My first review was on the Wotofo Bravo, where I enjoyed writing it so much and I thought im going to do this so I set up my website www.vapinbolt.comand started producing a blog where I have gained many different partnerships with companies and ongoing contracts for the future going forward Vaping is great and I thank the great community it has where I have built relationships from people all over the world and here in the UK Liquids are now my new venture to have a stable but evenly guide into the vaping world...
