Kayfun is pretty much trouble free once you get the hang of it. It's not a cloud blower because the air flow is about equal to a Nautilus or Aerotank Mega, but you can white out your face in a mirror and that's plenty of vapor for me. Kayfun is predictable and repeatable. It's easy to fill through the bottom screw hole, and isn't prone to leaking if you keep it upright as much as possible. I pocket carry mine and even lay it on its side frequently with no gurgling issues.
My EHPro Kayfun 3.1 has an adjustable air flow through a screw on the side. I've tried it in various positions, but settled on full open. If I need to juice up the wick a little more, 2 or 3 short, energetic puffs before the next vape will produce bubbles in the tank and a more flavorful vape on the next hit.
I transitioned to the Kayfun out of frustration with Nautilus and Aerotank Mega during the time when coils were lasting a day or less. That's been fixed with the new BVC coils for the Nautilus and the new dual coils for the Kanger Aerotank mega and various other models.
I have the new coils for both, but ended up sticking with the Kayfun. I can wind a coil and just change the wicks here and there as the flavor begins to wane. Changing a wick is a simple process after you've done it several times.
