Just how good or bad can a $1.78 DT-830B multimeter from AliExpress be?

Copper dust builds up and causes problems, such as BANG!!!. Low voltages, continuity and it's silly to expect much else for the price.

Most DMMs do these days, apart from some(?) Flukes.


EDIT: Check out some of Joe Smith's DMM robustness tests. The Agilents / Keysights are quite entertaining on switch wear!  https://www.youtube.com/channel/UCsK99WXk9VhcghnAauTBsbg/videos

I look forward to seeing these in the next Jaycar catalogue for $20 each

Looking around, it might be this one:

Since the 10A range is unfused with only a shunt, I wonder what would happen if it goes beyond 10A?  In the case of the HF meters, I afraid the probe wiring may act as the fuse, which can get ugly. 

The HF meters in the US is even more capable than the DT-830D+, as it can measure up to 750V AC, and 1000V DC!  If one is brave enough to try it with the provided probes.

I've been trying to find Big Clive's other trashy meter but it's not easy to get hold of at a reasonable price. If I lived in the UK I could get one but bot here in Spain. :-(

Farnell sells them for about $4 but I have to pay 15 Euros shipping. Maybe I could buy a dozen and flip them on eBay for a profit, keep one or two for myself.  :popcorn:
