I bought a vapor flask clone dna40 a while back and the temp control is right just for me. I know the Yihi Sx mini m class is out so for those who own or tried both dna 40 and sx350j, which one should I get?? I don't really care for the regular mode cuz I own a ton of regulated mod already. I probably will have those custom for dual 18650 but just need the right chip.
