I had a nemi with a hybrid cap short on me. I was my fault for not triple checking the taifun pin, it was too flush and shorted. It did not go to the extreme just got warm and deformed the battery. Now when I felt the heat I knew what I did and twist the body once to loosen and tossed it across my yard, lol.
To me doesn't matter how long you vape, when you get complacent things can and will go wrong. I also see (in my opinion) that some of these regulated mods are no safer than a mech.
Regulated gives some people, not all, a false sense of security. Electronics fail, fail safes fail, fuses fail, in short things can go wrong. One has to be vigilant no matter what device is used.
Safest way to vape with an APV is to learn as much as you can. Know your batteries, your Atty, your ohms, your device, and don't push it beyond the limits.
I have a small note book, cheap leather bound and fits in my back pocket. I write down what coil builds I like, juices, and any info I find interesting and/or important. It's a little cheat book, I even keep the ohms law calculations in it, just in case I don't have my phone around and want to know something.
In having said all that, I still use my nemi from time to time. If it was damaged though I would have tossed it like I did the battery. Inspect your gear, know your limits, and you'll never be 'that guy'.
