Been searching around and so far have only found the kayfun mini as a 14mm RTA. Is that a correct assessment? My friend only uses joyetech batteries but she loves the way my RDA and RTA hits. She doesn't want to move to a mech even a regulated one at this point so I'm trying to get a set up for her that is closest to mine. I already rebuild her kanger protank heads and she is happiest at 1.5 ohms so we won't have any issues there. I might be interested in picking her up one RTA and one RDA so when she gets new flavors she can use the one but when she's driving she can use the other. I don't care if they are clones, I actually prefer it as I am poor lol. Any ideas would be much appreciated.
