  • 2ml capacity
  • Designed for MTL vaping
  • Single coil builds
  • Flavour boosting design
  • Adjustable airflow

Creating better flavour from e-liquid is a key element of the Kayfun’s design, it does so in three ways. Firstly, the build deck allows you to fit smaller rebuildable coils that produce smaller amounts of vapour. The airflow structure concentrates the vapour produced and is fully adjustable to suit your vaping style. Finally, thanks to the full stainless steel construction, e-liquid is better preserved than it is in a glass or plastic tank.

The added benefit of RTAs like this is that you will experience enhanced flavour production, but it also holds 2ml of e-liquid so you won’t have to keep dripping as your cotton wicks will be constantly saturated. Refilling is simple thanks to the top filling design. For a cleaner look, you can use the Stainless Steel tank section or swap it out for a glass section.

Please Note: Every Kayfun Prime metal tank section features an engraving of a famous city name and emblem. Each city will be featured on a limited number of atomisers and in a celebration of Svoemesto's roots, the first five will be Russian cities, but all are unique and different.

Important information about Rebuildable Tank Atomisers:

Rebuildable atomisers are recommended only for experienced users. You should have the knowledge and access to the equipment that is required to set up this atomiser properly.

Before building coils or using an RTA you should have a thorough knowledge of battery safety, Ohm's Law and vaping in general.

Before fitting a coil onto your rebuildable atomiser ensure it is in a safe condition and registering the correct Ohmage, this testing and checking can be achieved by using a dedicated Ohmmeter. Coils should not be tested on vape devices.

Best MTL ever (12 June 2018)

I’ve had my Prime for about a month now. My first thought when I put it together was "this is a bit bloody fiddly", but ten minutes later I'd completely forgotten about that.
It’s taken me a while to get the flavour I wanted out of it, but now, every single vape of this beauty puts a smile on my face.
I was using the Nautilus 2 prior to buying this, which made my Manabush Spiritwalker Chiricahua taste incredible, but that juice (pretty much the only juice I vape) was killing the coil every 4 days. I’ve finally found that a 1.1 ohm 28 gauge Kanthal build, with Muji cotton, at 12 Watts gives me that flavour I’ve been chasing. On top of that, it’s a smooth, quiet, non-gurgling, no dry hits, no leaks whatsoever vape. I’m saving loads of money on coils. I change my cotton every other day.
Vapers, we’ve all been there - always thinking there is something better out there - but for the first time ever, I can’t imagine getting a better vape than this. It vapes exactly how I want it to. If I want to chain vape, I just open up the juice flow, lower the wattage a tiny bit (0.5 of a Watt) and chain vape. Not a dry hit in sight. If I lost this tank, I'd buy another without hesitation, and I’ve finally stopped looking at other vape products.
I also highly recommend finding the Ultem kit for this on eBay (Creme De Vape). It’s the same height, so no loss of flavour, but with a wider bore, so more like 3ml capacity. Looks very sexy, too.

Best vape (23 April 2018)

Having started on MTL vapes over 4 years ago I progressed to RDTA atomisers then to RDA atomisers and loved it for a long time. However recently the massive clouds and sometimes tight chest started to get to me. Also constantly dripping, filling up and changing batteries was a pain. I decided to go back to MTL vaping as before and what can I say, I’m so glad I chose this one! I have a few pricey vape set ups so wasn’t bothered about the 100£ tag on the Kayfun prime but compared to some of my others this hits them out the park. The flavour is amazing and the quality is insane. Perfect vapor and flavour with 70/30 and a 1.5 28g single.
Honestly, if your thinking about it and want it but are struggling to justify the price just go for it. You won’t regret it. Hopefully this will be my last tank for a while as I’ve never had anything like it.
Happy vaping !!!!

Isn't really anything better than this! (28 January 2018)

I bought my Primes from another vendor month ago however feel reviewing it here is essential, if you compare all the stats of this RTA it is actually worth £100, looks great, small, best machining I ever saw, perfect airflow, sublime flavour, wicks everytime, never ever leaks even if your a crappy builder.
If your a stock coil vaper who MTL vapes things like the nautilus or K2 then take the leap and buy this as a spool of 27g wire and bag of cotton has lasted me 12 months and still have a few months left of cotton (£8) for over a years worth of coils already justifies the initial (£100) as your saving money instantly, just need a build kit and your set up for life.
I personally won't ever buy another tank again, I've finally found what I need after 5 years of vape searching!

Brilliant Mtl (22 January 2018)

I bought this a few weeks ago from vape club and as usual the delivery was super fast. Ok it's pricey but the machining is superb as is the vape quality. Like the kayfun mini which i own it is really easy to build on. Single coil wrapped to give 1.5ohm is perfect for me. The main bonus of mtl vaping is longer battery life and you go through less juice than sub ohm. If you have the cash to spare then you can't go wrong with this tank, i have been using it since I bought it and have not had a single dry hit just great flavour. Highly recommended.
