Interesting conclusion... So a piston aircraft engine is always much better than a jet engine because of the number of parts???
Don't get me wrong, Fluke has great quality and they don't use this number of components just for fun. But Zoyi & co also performed greatly by providing quite a lot of multimeter for little money. That´s also a very legit and very welcome development target.

Well in a motherboard, the more phases you use, the more stabilised/perfect the proper voltage is... I imagine if you use more components, the accuracy should be higher.. it would be idiot using more components than needed just for "pleasure"

It doesn't work that way. I can design you a board with a hundred discrete TTL gates and analog switches, and do the same job as an integrated ADC with worse accuracy.

Nice, readable display, but the AAA batteries is a deal-breaker for me.

While they don't came with 9V (6LR61), no problem if AA, AAA or 18650

Rules and regulations are written in blood and usually have a reason. Meters being sold with lies on them about their safety is a big problem IMHO. People being aware of what is safe, or not, is a good thing. Ignoring rules just because ancient apes didn't have rules is not a good thing.

A problem about having a poorly built meter lying around is that people get lazy and might think "well just this time I will be OK" and then the next time and the next time until they get complacent. Another problem is with people who don't know better and believe the claims made on the ratings and safety on the multimeter and use it without thought that it might be a lie. Then there are some people who ignore any safety and properly made or no it won't save them.
This thread is a sticky for a reason. It may be out of date for current models but the reasons and information still are valid.

Definitely no discussion necessary - safety evolution is a great thing and without any of it at least half of this forum would probably be dead.

Sorry for being polemic here, but MAYBE the future of civilization would be even more granted if people do not absolutely arbitrarily plug in everything everywhere - at least on job sites. THINK before putting something on mains, and if you can't do that, then stay away 1m or more!
Of course, in companies with shared accident responsibility it´s different. There I also always recommend good equipment becuase luckily companies I work at can afford it. But if someone can't really afford it, I´d never complain about a "bad" DMM just laying around.
Or another provocative example: Bad luck can make your "wall wart" SMPS explode like a cheap DMM. Do you also equip *each* low power application with at least a CAT II fuse or charge your smartphone with a flashover suit?

This list is great, but because manufacturers are more or less lying about their products. Sometimes they lie so much that it is more than obvious - like a small €6-meter I have on my bench that is labeled as CAT IV 600V. I´m quite sure it´d be quite an incandescent device at the specified high voltage spike.
But others seem to be more beefy outside and aren't inside. These can really be dangerous e.g. at construction sites and there the list really may save lifes.
Fungus:
Flukes aren't magical. Procedure and knowledge is at least as important as the meter when it comes to safety.
The "safety" discussion has been done a thousand times on EEVBLOG and nobody ever changed their position AFAIK.
Getting back on topic: ANENG hasn't made an interesting new meter for years... :(
