Well...They just worked the way I liked straight out of the box.
I had been rolling my own coils with the PT minis for some time and I found the space kinda small so I got a subtank mini thinking it'd be easier to make and install coils.It was but it it didn't tootle the way I wanted and needed to be monkeyed around with.
Bought the Kayfun lite clone rolled my first 2.1 ohm coil (7 or 8 wrap 2.24mm diameter)fired 5.6 watts at it and it vaped like heaven,I then got the 3.1 Kayfun clone,it vaped the same as the lite but is a better machined clone and that's why it's my favorite.
It is a heavier atty but as a rule my kayfuns and subtank mini on my aspire pegasus don't leave the house,to darned heavy for my pants pocket.
When I'm out and about I still take my protank minis on a vision spinner battery and they still work great.
Thanks for the info! Very interesting. I don't build my own coils which is why I like the PT2's. A blister pack is under 10 bucks at our B & M. I usually get about 2 weeks out of 1 coil.
Is a kayfun lite clone strictly for those who build their own coils?
