Just how good or bad can a $1.78 DT-830B multimeter from AliExpress be?
Zenith:
It's the same as a lot of other things such as power tools, say angle grinders.
You could buy them for €14. Not very powerful and they didn't last long, switches broke and gears stripped. But for a one off job, or you wondered what it could do and how much you'd use one, fine. Arguably they were dangerous.
You can buy mid priced ones , €40 plus or minus, which put up with a lot more use and abuse.
You can spend hundreds on top end Makita etc. Lots of power, low vibration, full spares availability and they last for years. I'm not sure it makes sense to buy those, unless you are going to give an angle grinder daily use.
From my experience I wouldn't recommend anyone should buy the very cheapest, although I can see why people buy them.

Millions of people do it and live... :popcorn:

Very few deaths are caused by mains shocks.
It's the bang and the flash when these things arc over internally that some people have found disturbing.

I'm not sure where I could get one at that price.
On a related note: What's the best DT830?
Maybe this one: https://www.aliexpress.com/item/1005005195899615.html
It has ABS plastic, backlight, buzzer... doesn't say anything about internal fuses though.
Edit: Found a thread, there's no fuses.

That Aneng advert ^ shows a white LED plugged into the transistor tester and lit up. :)
Fungus:
Big Clive's other "trashy meter" with fuses and stuff is actually quite expensive:

factory:
This one on the right (DURATOOL D03047) was bought from CPC/Farnell in the UK in 2019 for £3.28+tax, it has a separate board for the jacks and a 5A fuse for the 5A range, it replaced an old faulty Hilka branded version which had no fuse for the 10A range.
