I had a close call today and killed my line....
At lunch, I was just about to leave my office and picked up my Darwin which was in it's case and it was red hot! As I picked it up, the drip tip melted free and fell onto my desk and the Line was red hot with juice pouring out.
The Arm was fully closed, but I suspect the combination of the Darwin switch not properly registering the arm closed, the case, the 510to510 adapter and the line tank Atty pushing the switch slightly was causing it to just fire constantly..
Now here's the scary part. Its only because I was heading out of the office for a few hours that I considered taking it with me since I usually take just my GTank and Sturm mod while out and about, luckily I thought, why not, picked it up and thank goodness, felt the heat. If I had not, I could have set fire to to office, potentially burning $1000s of dollars of tech equipment. .That would not have been very good. But the worst part, my colleagues are awesome and totally tolerate my PV usage, often commenting on how great my office smells, mostly vanilla custard, peaches and cream NY cheesecake home made juice. But setting fire to the office would have certainly put an end to my vape heaven.
Luckily, the Darwin is still working great as expected, I let it cool all afternoon.
But the Line, and in all credit, still delivers great vape, melted the silver wire insulation plastic and the window is constantly smokey and leaks now. Grrrr. Not an easy fix. Shame, because I really liked using the line on my Darwin, it allows the arm to close real easy and I keep the GTank on Sturm mod, with this setup, I have the ultimate, total low maintenance vaping experience..
So, just a word of warning to those of you also using tank attys with the Darwin, if the switch doesn't engage properly shutting off, plus you have the case on, not being able to see the illuminated screen, things can get toasty if you get flippant like me.
I was running 2.8ohms at 7.3w, I'm surprised the coil didn't burn out, or Darwin safety kick in. Both seem to be intact.
Be safe.
