I've become quite the fan of the kayfun Series. Just an outstanding device. I've spent a lot of hours with the KFL, but have recently acquired the 3.1. I enjoy them both. I do like the ease of filling in the 3.1; just poke and go. I haven't toy'd much with the adjustable air control; just tweeked it a little after receiving to see what the "blah" was all about. I will certainly purchase another I am sure, maybe a polished version..
They are a lot of money to be sure. But they are solid devices so you feel like you are getting your money's worth. This is not a device for frequent flavor changers. But for those who limit their flavors the kayfun is perfect and the return on investment is well worthwhile.
I have one flavor (HHV's, Dragon's Fire) that I vape 50% of the time. The remaining 50% is spread among a dozen other flavors. The KFL is dedicated to my Dragon's Fire. I use an assortment of RBA's, BCC's, and clearos for the rest. Seems to work out perfectly and all I need is one Kayfun Lite.
