So.....the SvoeMesto labeled Kayfun Lite from Focal may have "issues"? Will be watching for that when my order arrives, ordered 3 (ok, they were cheap and it's easy to spot quality control when you have 3 of those buggers!) The Marstech labeled KFL (yep, 3 of those puppies too) are working as flawlessly as my Tobeco KFL.....which is weird because after I got it, I checked out the Authentic Kayfun thread and it seems the original has some "problems"(shipping, airflow, insulator, blah, blah, blah)
Just running simple micro coils with cotton, had one instance of "user error" (always put them back together piece by piece to avoid miss-threading).
Ducking the tomatoes, but I did order 3 unmarked KFL+'s from e5cig, I know, pulled a Benedict Arnold.

For all means and purposes, it looks exactly like the Tobeco KFL+ and includes the same amount of extras: screws, hex bolt, hex wrench, wicks (I throw them away anyway)o-rings, screw driver, Allen wrench, and the same box. $15 and some change. Compare to $39-49 + shipping for Tobeco. I'll see how well they compare.
The biggest issue I see over and over with the original is the insulator between the deck and posts moves out from underneath the posts, haven't had anything like that happen with either the Tobeco or Marstech KFL's.
If all goes well, I should have enough KFL's to hold all my favorite juices, LOL!
