i was wondering this myself as im getting a kayfun clone and a good dripping atty when i get paid again...27 long days away.
Infinite Clones at Subsonic Vapes: Kayfun 3.1 = $23, Kayfun Lite Plus V2 = $22, Kayfun V4 = $40 ... shipping = $6 via Priority Mail.
Maybe there are better clones than Infinite, or just as good for a better price, but I believe that Infinite has better quality control (maybe I'm wrong, but I'm going with my belief)..
Would you rather own four different best quality 1:1 clones, or one authentic?
