My KFL impressions after a couple weeks with it -
Just for reference here are some of the RBAs I have owned -
Silica based:
GG Odysseus
GP Spheroid
GG Ithaka
Protank
Vivi Nova
Evod
Genesis based:
Z Atty Pro
Zenesis
RSST
AGA-T
AGA-S
Line SS
DID (the current king of vapor and flavor in my arsenal)
Drippers:
Various Igos (s,l,w)
Nimbus
Setup - the one thing I absolutely love about the KFL over the GG style silica based attys is the ease of setup. I'd say the Spheroid is just as easy but with less juice capacity of course.
Flavor - I find it performs much better with fruity flavors than with tobacco flavors in this regard. My 2 go-to tobacco flavors are quite muted in the KFL...this makes me sad.
Vapor - not as much as a dripper or a genny (esp. the DID) but the KFL produces an acceptable amount of vapor.
Throat Hit - the throat hit from the KFL for me is much drier than any other RBA I've tried....not sure why this is but no matter the juice, I get a dry scratchy throat after vaping the KFL (same with silica or cotton wick). I get this same dry throat from all silica based attys, but the KFL is to a higher degree. Gennys do not do this to me.
Juice Feed - seems to be hit-and-miss. I'll have a tank that wicks perfectly from beginning to end, then the next tank I'm constantly priming....dunno what's going on there.
Filling - kind of a hassle because you have to have a philips screwdriver nearby and a needle tip bottle, but doesn't really bother me since I don't fill when out and about.
Drip tip - the included drip tip doesn't work as well for me as a wider bore tip does, I get more vapor with the wider bore tips.
Construction - this thing is built like a tank, no complaints there.
After living with it for awhile, I think the KFL is just not for me. My DID (my all day atty) just works better, and for out-and-about I use an Ego twist + Evod which actually provides better VTF than the KFL, IMO.
My .02 cents.
Choice is what makes the world go around but I find the exact opposite as you. I get good flavor from my tobacco juice. I don't vape anything but tobacco juice and the craziest I get is RY4..
I get plumes of vapor.. So much so, that at times it's too much as I don't want a fog machine..
I get mega throat hit and I have found that the KFL is a nicotine delivery machine. I, along with many others, have to go down to a lower nic level with the KFL.. When I drip, I use 18mg but when I use the KFL I bump it down to 12mg..
Juice feed is highly dependent on the build. I have had good builds and bad builds. The juice flow is VERY dependent on how good or bad the coil and wick build is..
For reference I have had the following and I find that the KFL is hands down my go to RBA with large tank.
Ithaka
Z Atty Pro
Kayfun Lite
Diver
Grail
Cyclone
Immortalizer
And a few others that I am sure I am forgetting..
The KFL is an awesome RBA but it is very, very, very dependent on the coil and wick build.. Get that right and it's vaping bliss...
