The Kayfun 4 Review By Nick Bessette – Spinfuel’s Daily Vape TV
This one is for all you tank lovers out there. If you’ve ever wanted an authentic Kayfun but hated the fill/airflow mechanism then the Kayfun version 4 might be worth another look. In this video, I show you the finer points of this gorgeous feat of engineering genius, build it and go over what I think they did right and what still needs to be improved upon.

SvoëMesto redesigned the Kayfun and incorporated many of the features customers have said they would like to see in the next version. The Kayfun V4 is made from medical-grade 316L stainless steel and offers 3 tank options: glass tank, polycarbonate tank and a steel tank. Filling is easier than ever before; just unscrewing the drip tip will do it.
The Kayfun V4 offers eliquid flow-control built-in. You can access the deck without having to empty the tank, and it gives vapers the option to shut off liquid transfer completely in order to get to the deck and prevent leaks. The air flow on the V4 has been improved immensely to provide even more vapor production than the Kayfun v3. The Kayfun V4 deck has 4 coil screws for dual coil builds as well as single coil builds.
When available the Kayfun 4 is $180.
