Everyone says a DNA or Yihi mod is overkill for low watt, MTL vaping. Anthony posted that as recently as a week ago on Reddit. From my own experience with MTL vaping, I have to disagree with everyone. The Kroma-A I bought with a Zenith tank did much better than the Sigelei MT did with the Zenith and Vapefly Nicolas tanks but much worse than the HCIGAR VT250S. The MT reads coil resistance way above rated resistance and blows out coils right after installing them regularly seemingly from too much power too quickly. The Kroma-A usually read resistance somewhat above rated but sometimes at and once or twice just below. Coils at least consistently lasted for a half a week or so on the Kroma-A and rarely seemed like I got a dud unlike with the MT. The VT250S has read every coil I put into the Zenith tank somewhat below rated resistance. Each coil has lasted at least a week with the DNA mod. The vaping is such a slow, steady, smooth vape on it. The Kroma-A seemed a bit erratic but at least it wasn't applying far too much power like the MT does. If anything, slightly too little a majority of the time. The VT250S seems consistently near perfect every time. I don't remember much with the Vivikita Move60 but it seemed just slightly better than the MT. There does seem to be a very noticeable correlation with how well a mod does TC with how well it does MTL. VT250S (excellent TC mod) > Kroma-A (good TC mod) > MT (bad TC mod). Maybe there isn't much of a difference vaping in watt mode between mods at higher power but there sure does seem to be with low power MTL vaping as counterintuitive as that seems. Maybe margin of error ranges mean a higher percentage margin of error at lower power like a watt or two or maybe with resistance readings on clearomizer coils needing to be more precise; I just don't know why. I just know that the better a mod does TC, the better it seems to do MTL -- at least with clearomizer coils like Vapefly Nicolas and Innokin Zenith. Maybe this needs to be tested more thoroughly. Maybe it is just my imagination wanting something better out of better mods but I really don't think so. Any feedback on this would greatly be appreciated. I'm at the point where I need to buy a backup mod and only want to buy either a DNA or Yihi just to vape nic salt in a clearomizer. I am reluctant to buy even a Vsticking since the SX530 chip is rumored to lack 16 bit resistance sampling like the G Class mods with SX550j chips do. Please help! Let me know if I am onto something real or about to waste triple figures on confirmation bias.
