All the larger manufacturers of "consumer" vape gear have had, or are having, issues with QC resulting in a higher fail rate. Sometimes, it's one company, then a year later they're great, and vice versa. I have an Alien and an AL85. They're both nice mods. My finish has held up. But I also don't push them to run crazy high wattage all day, even with batteries that can supply the current to the board.
Still, I wouldn't recommend them for temp control to anyone as they both suck at that. I will admit that if my mod started smoking and melting sitting on the coffee table I'd sure lose faith in that mod brand and not accept a replacement for it unless it came with a Class D fire extinguisher. I understand there may be tens of thousands of others that are fine, but I would use that one experience to ban that brand from my home, never mind my pocket. It might not be valid based on data, but that's where emotion takes over.
