No, but I do recognize they can be dangerous and so take reasonable precautions like unplugging them before trying to get toast out with a butter knife etc. 120v rarely kills people, but saying that does not mean it's 'safe'. https://xkcd.com/795/
You've totally missed the point. Yes toasters can kill people, but statistically very few deaths are by toaster. That's why as a society we've decided the useful convenience of toasters outweighs their inherent dangers. Similarly, we've decided that really cheap meters are beneficial enough to outweigh the slight possibility that someone might measure a too-high voltage while using the meter as an eyeshield or baby toy or something.
Safety is far from a binary thing. People used to build extremely unsafe toasters that changed over time in large part to government rules and regulations. We accept cars and trucks killing 30,000+ people in the US every year, but even that number is much smaller than it could if we let company's sell cars like they where designed in the 1950's or let people drive like they did back then.
We accept that cheap electronics are going to be somewhat less safe, but we don't accept people selling cheap electronics leaching off the reputations of high-quality brands. Not just because it can kill people but it also creates bad incentives where there is little point in creating quality if nobody can tell the difference.
And no they did not just randomly chose to have a yellow back it's a deliberate imitation of a quality product which could easily cause confusion in the marketplace and kill someone.
This subthread is about "safety", not trademarks. IANAIPL, and I have no opinion about what color the various cheap-ass meters I have used should be. If someone is too confused to contrast the letters comprising "Fluke" from those comprising "Mastech" or whatever, that someone is too confused to be metering circuits.
For my edification, can you point out one example of a human being who was killed while using a cheap meter, who would have been unharmed if using a precious Fluke?
I'd still like to be edified. How about one example of a human being who was injured in any way while using a cheap meter, who would have been unharmed if using a precious Fluke?
