Ok lol. All I'm seeing is opinion based debates. If you want to prove something, use facts. I have some opinions on my experience.
I like the sx350j more because of the menu options. I love the presets. It's easier for me to navigate than the dna 40. I can leave the device unlocked and not worry about power changes or accidental firing because of the buttons being almost flush and the amount of force needed to press the buttons. This is my opinion. Some may prefer the dna 40 menus. Everyone is different. I'm not going to convince a dna 40 lover to like the sx board more if they can't like it more. It's like trying to make an atheist believe God. It's just not going to happen.
I have wonderful experiences with the squape r. The non conductive coating is not an issue, the center 510 pin is. I've stuffed a few strands from silicone wire between the threads and bam, no more resistance fluctuations. I run 28 guage ni200 at 6 wraps getting me at .075 ohms and it's perfect for me. Running it at 13-15j is awesome. But that's for me. I love the fact that I can switch between 13j and 15j with ease. I tend to vape at 13j in the morning. I've only seen it go past my set 420°f to 425°f at the most, and that's at the end of the week when my coil is all gunked up. My only gripe about this mod is that it chews threw batteries a little quicker than the dna 40. My battery lasts me all day and into the morning anyways and then I change it out before I go to work. This is my experience and your results may vary because everyone vapes differently.
If you don't like the sx350 mini j, why are you in this thread? In other words, If you're an Atheist, why are you going to church?
