Ok ground is fixed.
And I got a good coil on it finally. I agree 100% Vapenstein the smoked screen sucks but I am digging the Mod.

Looks great. Much cleaner looking than my attempt. Glad to hear you've found a build and setting that you like. I'm haven't had enough free time to really find a sweet spot for me. I've only tried it using single coil Ni200 28GA (Temco) in a dripper. Hopefully I'll find some time this weekend to try some other things including an RTA.
Ok so I scrolled through some pages and I apologize if this has already been addressed. I really want to get a DNA 40 device but I'm really hesitant after Busardo's review. I know he didn't test this device but are you guys having the issues he was with other devices as far as it getting stuck in TC mode or the refinement problems? I'm really glad I found out about those issues because it seems like some major PITA stuff! Kinda off topic but you can't make a contact coil with nickel? Thanks for any help. I think the price is great for this device but I just don't want something that will add unnecessary stress to my life. I'm aware of the ground issue. No biggy there.
Sorry I probably won't be of much help, but my suggestion would be, if this would be your only device, you may want to wait. Not because I dislike the device, I actually have a second on order. But it does seem to be a little finicky in TC mode, but not enough to dissuade me from playing with it more. I haven't used it outside of the house, because I'm still in the playing with it stage and if I find a build and topper that seems stable enough then I would feel more comfortable taking it on the go. But I would probably have a back up device, just in case.
If you already have a regular device and you want to try a DNA 40 device just to play with TC, I would say go ahead and pick one up. Although the safer route would probably be waiting about 2-3 months to see how all of the TC devices shake out. I'm really curious how the Yihi chips perform and will probably pick one up within the next 3 months. It sounds like Yihi will have a budget TC chip available next month, the only drawback is no step down, but if you usually vape over 4V, then this probably wouldn't be an issue.
I haven't tried mine in non-TC mode, but from what Vapenstein has written, it sounds like a winner. So I don't know if mine will run into the problems of getting stuck in TC or non-TC mode. I really like the fact that it has proper step down. I'll eventually try non-TC mode, but it's not a priority since I still have my other devices. I haven't run into the refinement problem, but I also haven't experimented with it enough.
From reading around, the DNA40 devices do seem like a PITA. I've purchased a few different drippers and toppers to experiment with. Unfortunately, I'm inherently lazy, so who knows when I'll get around to trying them all. I still have RTA's that I purchased in February 2014 that I haven't used.
I haven't tried contact coils yet. All of mine have been spaced. And from what I've read and watched on youtube, it seems like that's what we're suppose to use for TC mode. But I'm not 100% sure. The ONLY problems I've had so far with the device is my first coil build, I used the post holes and didn't make good contact with the wire. Resulted in weak vape. Fixed this by trapping wire under the screws on top of post holes. Second was when I was too lazy to wait for my Samsung 25R to charge on my external charger and put a newly charged Efest purple in it. For some odd reason the device was firing over my wattage setting and the coil was definitely HOTTER than what I was use to. Only tried it for about 5 presses of the fire button. Took out Efest, put back in the charged 25R and it was normal again. I have no clue why. So I haven't tried the Efest since then.
The price on the device was the reason I jumped on it. Plus how clean the inside of the box looked. I have a feeling there will be a ton of TC devices by the end of the year, so there's probably no hurry to jump in. From the tone of your post above, I would suggest waiting. If you absolutely NEED a device now, there are a ton of cheap, well made devices on the market now that will hold you over until this whole TC thing shakes out. Just my opinion.
