DNA 40 boards stil giving problems

I just skipped to the numbers and then straight to the end of part two

 

I must have 2 really good DNA40 devices. No screen issues, no temp changing/refinement problem, no sticking in temp mode problem and the battery bar hasn't caused me a bit of grief either. My only disappointments are:

Working with Ni200 and the space and care it requires. Kanthal a good amount easier.

With a good number of RDAs I have difficulty with or cannot obtain the warmth and density of vape I want. Some RDAs work very well with it though.

I skipped around but headed for the end quick...his seal of disapproval will hurt a bit me thinks

 

You'd think it would but I don't know. Everything that has been said about Evolv in the past year or so has always been great and how these guys are geniuses and yet they failed until recently to even have reverse battery protection on their boards.

I don't see temp control going anywhere until someone comes up with a way to relate it to kanthal...then we have a ball game.

 

Well my VF had all the issues mentioned, and I agree for my drippers it was good. I hope when it gets back to me the problems have been solved. I now have a second one, big screen to get frustrated over. Chucked it into a box today and so far its OK. Just need my NI200 OCC coils next week now, but no rush if V is out of action, I have 2 tanks and 4 drippers already coiled.

 

I personally have never experienced this. If anything, with both of my DNA 40's, it is noticeably cooler than tank temps I'm used to with Kanthal. Maybe this is an indication of some inaccuracy in readings or something else? Maybe it's the attys in question? I know you are a fan of the Rose V2 as am I but honestly, I have yet to do a Ni200 build on one yet.

 

All ok now but, I think we've heard that before.

 

Interesting we have a refinment feature that causes problems so lets just lock it out

 

I think they are also bringing attention to the fact that it is poor/unstable atty connectivity and coil connections that are behind the refinement process changing values. Not really a refinement problem. These connectivity type issues have long been pointed out as a potential problem that needs to be considered when building the coil, securing coil legs and also in considering the quality of your atty's connections.

The flip-side to this is that if you have a less than stable atty or atty or generally, something happens to change the resistance of your setup, your "locked-in" setting could be inaccurate relative to actual resistance at the coil. At the heart of all this is Ni200 and greater challenges in building and securing a good coil in the atty as well as the low resistance levels to begin with where with what would be a negligible difference in resistance using other coil metals can be a significant difference with Ni200.
