I bought a clone on eBay, it vapes well enough, but it's jankey. The AFC and the JFC's aren't smooth, and it wobbles on every mod I've tried it on. Not knocking clones, because I know for a fact that there are several who've found good ones.
The description didn't list the clone maker, and nothing on the boxes to indicate the maker.
Oh, and it also needed several hot water Dawn baths.
The one I got Tues. was an authentic from HHV, and prob my last vape "hurrah" so to speak.
It's very nice, as expected.
I have to say though that I'm really loving my KFL+'s.
That's just a darn good vape, (for a tootle puffer) and the more I use it, the more I really love it.
