great topic. I think a lot of people do speak softer when comparing DNA vs Yihi. I think people don't want to bad talk DNA too much since there's a lot of fans of the chip as well as it's an American made technology that WAS the best in the industry TC wise.
But I think we need to continue being objective or else our favorite company won't evolve (pun intended). Plus a lot of folks don't like the idea of China being better than USA in something that was once FAR ahead of every other in vaping technology. And China was only a cloner and stigma with inferior mass produce products. Leave resentment and denial of DNA objectively. This of course is just my observation and opinion, please take it as just that.
With that intro, I can now tell you I think Yihi Sx Mini Q Mini is a superior product to any of DNA chip. There are graphs and charts for that as well. A DNA chip can't do true 250, only 167 with 18650. A Q mini can fire 200 watts max all the way till battery life is gone. Yes, it doesn't get weaker, it fires true 200 watts until batteries are depleted. Yet DNA can't even do 200 or 250 watts with full batteries charged. Now wattages is not the only judge of quality but it's something worth mentioned.
With yihi style of TC makes more sense to me and that's why battery life is better. You slowly raise the joules while setting your perfer temperature. And this is also why Yihi looks bad when Phil was doing his reviewed. He max the Joules and then set his temperature. So he sense and hear "hissing, pulsing," and other not good results. You cannot use another product intended procedures and say it's a fail with another. Imagine if u set wattages on DNA low and locked temp. DNA function well setting high wattage if not Max wattage and then go in TC mode. You get a strong vape that way. I think Phil is very biased of Yihi vs DNA debate as well, but that's another story too long. If any one interested please asked why I feel that way.
and the biggest one I can do everything Evol can do on my Q mini. I do not need to hook it up to a computer. It be more tedious yes, but th device right out the box can be customized to the end user without pc. You can change your profile settings etc all on the Q mini mod. That's a big thing to me because I believe a Mod shouldn't rely a PC connection to reach its potential. The user should be able to vape right away. And if customized is what is wanted, it can be done not even same device without being reliant of other sources.
Last a lot of people say Bluetooth app for iOS is a con because it's only for Mac. I understand there's more andriod users. But see it from this view: if you have a pc you can download sxQ software and customize your mod. if you have a Mac, you can use the Bluetooth app. So in a way Yihi covered both platform. While Evol DNA still don't have a Mac software. Think of it in this perspective.
Sorry for the long posts. These are just some of the points where I think Yihi is the better device/chip.
To a better vape,
