SvoëMesto Kayfun 5²   


The Kayfun 5² is a bigger version of the Kayfun 5, combining simplicity, functionality and outstanding performance. A fully adjustable liquid control gives you full control over your liquid flow, however, thanks to SvoëMesto’s pressure based feeding system, fine tuning is not required with the majority of setups. After closing the liquid control, the Kayfun 5² can easily be filled through the top within a couple of seconds. Just as simple as filling it, is accessing your coil by removing the tank, regardless if it’s filled or not. The build deck has been enlarged to fit complex builds like clapton coils more easily.  At the same time SvoëMesto has increased the adjustable airflow to a maximum of 4mm, providing more even more airflow for high performance builds.

The airflow control can be adjusted in 3 different positions:

  • 3 mm
  • 3,5mm
  • 4 mm

The internal design of the evaporation chamber has been optimized to create an outstanding flavor profile, Kayfun fans have grown to love, even at higher airflow settings.

As with previous models, the Kayfun 5² only utilizes highest grade materials. Thanks to its intelligent design, cleaning and maintenance can be done by disassembling the atomizer into no more than five pieces, no tools required.
It’s functionality, intuitive handling and rich flavor profile combined with great performance capabilities make the Kayfun 5² a true daily driver.

  1. Great RDL review by Patrick on 8/17/2020

    Amazing flavor banger that brings out notes in juices that other tanks can’t. This is a restricted direct lung, so don’t think loads of airflow. Just enough for a good smooth and warm vape. Tank is also huge so really for home use, on a side-by-side mod, or pick up a Steam Tuners nano kit.

  2. Love it review by Eric on 6/9/2019

    Best rta I've ever owned,flavor is on point and no dry hits since I've used it. I know its pricey but ita well worth the money

  3. Everything you'd expect review by Kevin on 4/22/2019

    It's a Kayfun v5 with bigger airflow, bigger juice intake and bigger build deck. Yeah, it costs a lot but you truly get what you pay for. Just forego buying the next 5 junky Chinese RTAs that you'll eventually hate anyway and buy this instead. You won't regret it.

  4. Best kayfun yet. review by Gary on 11/12/2018

    I have owned two Kayfun v4 and A v5. There were issues with both previous models. This v5² square is the best yet, bigger build deck for fused Clapton coils, and it wicks extremely well. I even set it in my cup holder and took it for A ride in my vehicle and it didn't leak. (most rta's will leak every time in A vehicle) More airflow is nice for lung hits. dicodes-usa shipped it to me very fast, most other online places take A week or so. I highly recommend you getting this kayfun v5² square and buying it from dicodes-usa
