Update on my issues. My mod will be going back to Hana. RMA form was sent this morning. I did mention somebody with the display glitch could duplicate my problems though mine hadn't had that issue.
I have two DNA 40 devices. One xpv purchased the day of release and delivered ten days later. I have not had any issues with it in any way or under any operating condition.
I also have a vapor flask that I purchased a few weeks after and again, no issues under any operating condition.
Either I am the luckiest vaper ever or we only hear about the problems on our forum.

Bass,
I think it is pretty common that "we only hear about the problems on our forum". The folks that have DNA40 and are happy don't usually come here to brag about how well it works but let someone get a unit with a Glitch and they (me included) will come complaining about issues.
So looking here for "Reviews" can tend to be lopsided to the negative or at least appear that way.![]()
I'm pretty sure he was replying to my comment, asking if the issues are widespread, and if there was any way to see if mine was affected or what kind of things I should be looking for.

I just got my Vaporshark rDNA40 Monday, I had not heard of the issues with the DNA 40 until now checking out this thread. My VS seems to be working fine right now, I don't see any problems with the display, but I never vape above 20 watts. The temp protection seems to be working fine, and the DNA seems to be reading my nickel coil accurately. I do sometimes see the base resistance change by .01 or .02 occasionally, but only when the device has been sitting and I have to wake it back up, I guess it rereads the nickel coil and we all know the nickel wire resistance is constantly changing (which is how the temp monitoring works). Is there a way to check if mine is having any of the issues? I saw about firing the device at 40 watts and seeing if theres eventually a problem. But since my device is working great right now, I don't want to CAUSE the glitches. How widespread are the affected boards?
This is a long thread, I tried to go through some of it to see if I could find some answers, but I really don't have the time to read through this whole thread to get a good idea of what the issues are and how widespread it is. Thanks.
Some additional thoughts designed to help you. Vape and enjoy your new VS 40. Period. Tune for the flavor of your vape, your required vapor production, and the various lengths of your draws throughout the day. Using a dripper, the TP warning will appear as your wick begins to go dry. An actionable event displayed on the screen which tells you to drip more juice. That's the way it's supposed to work and does work. No need for you to engage in any contrived and specious tests to see if your device is defective. From reading your posts it appears to function exactly as Brandon and John desgined the 40. On the other hand IF you get a garbled/wonky screen then by all means post. In this case that occurrence still does not mean it's a defective 40. In short, enjoy and vape.
Ignore the following tangents in this thread:
Attempt to make the 40 do something it was not designed to do
Contrived "tests" which produce specious results
Wild and unsubstantiated "connecting the dots" myths
Posts from folks who don't even own a 40
Good luck and don't hesitate to send me a PM if the "noise" in this 50 page thread confuses you. If I don't know the answer I can always ask an authoritive source.
EDIT: Ditto to my fellow early adopter @Hollman. AND, NO ONE on the face of the planet earth except Evolv can tell you exactly and precisely what the incidence of failure of the 40 is. Period. Ignore all posts that attempt to quantify (with numbers and or percents) this issue unless they are made by Evolv.

On my DNA40, no, but I've previously fired it on a DNA20 and a mech and it didn't catch fire. It just made plenty of white oxide, see my blog. I do like it on the DNA40 'cause it's not soft like nickel (in fact it's the opposite, perhaps a bit springer than optimal), it does run fine in temperature mode (although you have to use a lower temperature), it's got a higher resistance (meaning you don't need over-sized coils) and last but not least, it doesn't irritate my mouth and throat like both nickel and nichrome seem to.
maybe brandon and john didnt plan on us using our dna 40 devises out in the cold weather. guess mine works just fine as long as i stay inside!!!!!!! YRMV
lots of electronics are exposed to cold temperatures without problems. does you car radio work in the winternow batteries is a different thing but we're not discussing batteries in this forum. just expressing my dissatisfaction of this devise not working when it gets a little cold. yes it needs to be rma'd but till i know that others are rmaing theirs for the same issues. im not sure evolve knows some dont work outside and if they will exchange it for one that works properly

I agree (yes, I'm one of those guys that hasn't received his dna 40 board yet but is posting on this thread).I received mine after doing considerable reading of this Forum while waiting for the pre-order to complete. The negative reports of early-adopters (rDNA 30) concerned me as they apparently do you. So, I did a very straight-forward, easy, test upon receiving the rDNA 40:
On a Ni200 build at 0.16, I set the VS rDNA 40 to 40 watts, stood in front of the bathroom mirror, and repeatedly fired the device...vaping it. I received no warnings or error messages, other than TP (Temperature Protection) notification. After doing this on and off for a couple of hours, my mind was set at ease. I have experienced no problems to-date.
Seems a silly thing to do, but I have always preferred "my lying eyes".![]()

And unless I'm misinterpreting the Wikipedia article on titanium, that oxidation doesn't occur until 2,190 °F...

...which implies without TP that coil must be hitting at least 2190 °F...
Based on the colors I saw the wire glowing, I don't think it was that hot.
